Hip dysplasia in cats: symptoms, causes, diagnosis and treatment

Your Maine Coon used to vault from the floor to the top of the bookshelf without a thought. Lately he uses the chair, then the desk, then the shelf, in three slow steps. He pauses before he jumps down from the bed. He sits funny — one back leg sticking out to the side — when he washes his belly. When you scratch the base of his tail he tenses, and once or twice this month you have found a small puddle on the floor an inch outside the litter box. Nothing about this looks like a broken bone or a torn ligament, and that is exactly the problem. Your cat may be living with hip dysplasia, and unless you and your veterinarian go looking for it, no one is likely to find it.

Hip dysplasia in cats is one of the most underdiagnosed orthopedic conditions in feline medicine. For decades it was thought to be primarily a large-breed dog disease, and most veterinary teaching reflected that. But studies using hip X-rays as part of routine senior screening have repeatedly shown that hip dysplasia is far more common in cats than anyone realized, with prevalence in some breeds approaching one in four cats. Despite those numbers, most affected cats are never diagnosed. They are simply called "slow," "lazy," or "just getting old."

This guide walks you through what hip dysplasia actually is in cats, how it differs from the version most people associate with dogs, which breeds are most at risk, the subtle senior-cat signs that point to it, how veterinarians diagnose and grade it, the full range of medical and surgical treatment options, and the home modifications that meaningfully improve quality of life. The goal is to help you recognize a disease that has likely been hiding in plain sight, so your cat can spend her senior years as comfortable as possible.

What hip dysplasia actually is

A healthy hip joint is a ball and socket. The rounded head of the femur (the thigh bone) sits deeply inside a cup-shaped socket in the pelvis called the acetabulum. Strong ligaments and a smooth, cushioning layer of cartilage hold the two surfaces together so they glide against each other with almost no friction. In a young, normal cat, this joint can absorb the impact of jumping six times its own height and rotate through the full range of motion needed to climb, crouch, twist, and groom.

Hip dysplasia is a developmental condition in which that ball and socket do not fit together correctly. The acetabulum may be too shallow, the femoral head may be misshapen, the ligaments holding the joint together may be loose, or all of these problems may occur at once. Instead of gliding smoothly, the femoral head rocks and slides within the socket each time the cat moves, and that abnormal motion damages the cartilage over time. The body responds by laying down new bone around the edges of the joint, thickening the joint capsule, and producing inflammatory fluid. The end result is osteoarthritis: pain, stiffness, reduced range of motion, and progressive loss of function.

It is important to understand that hip dysplasia is not an injury. A cat is born with the genetic predisposition for it, and the abnormal joint architecture develops during the first year or two of life. The arthritis that follows, however, often does not become clinically obvious until the cat is much older — sometimes not until the senior years, when years of accumulated cartilage damage finally tip a quietly compensating cat into visible discomfort. This is why so many cases are diagnosed for the first time at age 10 or 12, even though the underlying joint problem has been present since kittenhood.

How hip dysplasia in cats differs from the dog version

Most people's mental picture of hip dysplasia comes from large-breed dogs — German Shepherds, Labradors, Golden Retrievers — who develop a recognizable swaying gait, a reluctance to climb stairs, and a dramatic limp in the back end. Cats with hip dysplasia almost never look like that, for several reasons.

First, cats are small. Even a large Maine Coon weighs a fraction of what a Labrador does, which means the mechanical load on a dysplastic hip is correspondingly smaller. The same anatomical abnormality that would cripple a 90-pound dog can be remarkably well tolerated by a 12-pound cat for years.

Second, cats are physically gifted. They distribute their weight across all four legs more evenly than dogs, they have an incredible ability to compensate by using shoulders and forelimbs to take pressure off the back end, and they can quietly modify their daily lives in ways that make pain easier to live with. A cat does not need to walk on a leash, climb into a car, or take stairs on demand. She can simply stop doing the things that hurt.

Third, and most importantly, cats hide pain. In the wild, a cat who shows weakness becomes prey. That instinct is wired deeply into feline behavior, and our domestic cats still carry it. They do not whimper. They do not limp dramatically. They will not come to you and tell you a joint hurts. Instead, they quietly rearrange their world to avoid the movements that cause pain, and those small adjustments are easy to misread as personality changes, "mellowing with age," or simply slowing down.

The result is that hip dysplasia in cats looks less like a limp and more like a cat who has become a smaller version of herself: less active, less playful, less interested in vertical space, less willing to be touched in certain places. That is the picture to learn to recognize.

Which cats are most at risk

Hip dysplasia has a strong genetic component, and certain breeds are clearly overrepresented in studies and in clinical practice.

Maine Coons sit at the top of the list. Multiple studies have found radiographic hip dysplasia in 18 to 24 percent of Maine Coons, with some lines showing rates higher than that. Their large size, slow skeletal maturation, and genetics combine to make them the most reliably affected feline breed.

Persians and Himalayans are also frequently affected, in part because they share genetic background and selective breeding for body type that influences joint shape. Persian-related breeds, including Exotic Shorthairs, share similar risk.

Devon Rex and Cornish Rex cats, despite their small size, show higher rates of hip dysplasia than the general feline population, likely related to selective breeding within a relatively narrow gene pool.

Scottish Folds deserve a special note. The same gene that gives them their characteristic folded ears also produces a cartilage disorder called osteochondrodysplasia, which causes severe, painful joint disease — including the hips — often beginning at a young age. Scottish Folds may have hip dysplasia and several other joint diseases simultaneously, and clinical signs frequently appear well before the senior years.

Siamese, Burmese, Abyssinian, and Bengal cats are also reported at somewhat higher than baseline rates in some studies.

Domestic shorthairs and longhairs are not immune. While prevalence in mixed-breed cats is lower than in the breeds listed above, mixed-breed cats can absolutely develop hip dysplasia, and because owners are less likely to suspect it, these cats are often diagnosed even later in life. Any senior cat with mobility changes deserves to have hip disease on the differential list, regardless of breed.

Other risk factors layered on top of breed include rapid kittenhood growth, excess weight, neutering at very young ages in some studies, and previous trauma to the pelvis or hip joint. As with most orthopedic disease in cats, obesity is a major accelerator: every extra pound adds load to an already-abnormal joint, and excess fat tissue also produces inflammatory chemicals that worsen the underlying arthritis.

The subtle signs in senior cats

Recognizing hip dysplasia in cats is largely a matter of noticing the things they have stopped doing and the small ways their movement has changed. Each of these signs in isolation can have other explanations, but a cluster of them in a senior cat — particularly a predisposed breed — should always raise the question.

Reluctance to jump, or changes in how they jump

This is often the first and most reliable sign. A cat with painful hips does not simply stop jumping; she breaks the jump into pieces. Instead of sailing from the floor to the countertop, she jumps to the chair, then to the counter. She hesitates at the edge of the bed before climbing down. She no longer uses the top tier of the cat tree. She may abandon the windowsill she has loved for years because the climb is no longer worth the reward. Some cats get stuck on surfaces they used to come down from easily and cry to be lifted off. Owners who note these changes early are often the ones whose cats are diagnosed at a stage where treatment is most effective.

A "bunny hop" gait

Some cats with bilateral hip dysplasia move their back legs together rather than alternating, especially when moving faster or climbing stairs. This bunny-hopping gait is the cat trying to spread the painful work of pushing off across both hips at once instead of loading each one individually. It is more obvious in larger cats and in those who still try to run, and it is easier to see from behind on a smooth floor.

Stiffness after rest

Watch your cat the first thirty seconds after she has been lying still for a long time. Cats with hip dysplasia are often visibly stiff when they first rise, taking a few slow steps before loosening up. They may arch the back, stretch awkwardly, or sit halfway up before fully standing. They look like an old person getting out of a deep chair, and it means what it looks like it means.

Changes in grooming

Grooming the lower back, hips, base of the tail, and inner thighs requires the spine to twist and the hips to flex through their full range of motion. Hip dysplasia makes those motions painful. Cats with hip disease often develop matted, greasy, or unkempt fur over the lower back, rump, and tail base, which are the very areas hardest to reach. Some cats overgroom one specific spot — often a hip — leaving a thin or bald patch as a focal sign of pain. A few cats stop grooming everywhere, and their coats simply look untidy in ways they never did before.

Litter box changes

Squatting to urinate or defecate loads the hips and lower back. Stepping in and out of a high-sided box requires hip flexion and extension. Cats with hip pain may begin to urinate or defecate with their back end overhanging the edge of the box, eliminate just outside the box, miss with one part of the body, or stop using boxes that were previously fine and seek out softer, lower targets like a rug or the bottom of a closet. Inappropriate elimination in a senior cat should always trigger a question about whether hip disease or other arthritis is contributing, because so many of these cats are misdiagnosed with behavioral or urinary problems when the real issue is that the box hurts.

Reduced activity, play, and climbing

Cats with hip dysplasia simply do less. They sleep more, play less, and shorten their play sessions when they do engage. They may still chase a feather wand for a minute when they used to chase it for ten. They may stop climbing the cat tree they once owned. They may no longer ambush their housemate from on top of the cabinets. Because the change is usually gradual, many owners write it off as the cat "mellowing." In a predisposed breed, that mellowing is more often pain than personality.

Changes in sleeping spots

If your cat has always slept on top of the wardrobe and now sleeps on the bed, or always slept on the bed and now sleeps on the rug, ask why. Cats with hip pain seek low, soft, warm places they can reach without effort. A cat who has migrated downward in your home over months has often migrated downward because the climbs hurt.

Sensitivity around the hips and back

A previously friendly cat who now flinches, tenses, swats, or hisses when touched around the hips, lower back, or hindquarters is almost always telling you something hurts. The reaction may be mild — a quick muscle twitch, a tail flick, a head turn toward your hand — but pay attention. Cats are not subtle out of dishonesty; they are subtle because they have to be.

Muscle loss over the hips and thighs

When a cat stops using her hindquarters with the same vigor, the muscles there atrophy. Run your hand over the tops of her hips and thighs. If the bones of the pelvis feel more prominent than they used to, or if the muscle mass over the back of the thighs feels hollowed out compared with the front legs, that loss reflects chronic disuse from joint pain.

An abnormal sitting or lying posture

Some cats with hip dysplasia sit with one or both back legs sticking out to the side rather than tucked neatly underneath, because tucking the leg requires hip flexion the cat is avoiding. Others lie almost exclusively on one side rather than rotating between sides, or stretch out flat in a posture that puts the least possible pressure on the hips.

How hip dysplasia is diagnosed

Diagnosing hip dysplasia in cats is a combination of detective work and imaging. There is no single blood test for it, and many cats resist the manipulation needed for a thorough orthopedic exam. The process usually involves your observations, a careful physical examination, and X-rays.

What you bring to the appointment

Because cats often hide their symptoms in the exam room, your observations are the most valuable diagnostic information your vet has. Before the appointment, make notes on the things your cat has stopped doing, how her jumping has changed, any litter box misses, grooming changes, sensitivity around the hips, and any specific moments where she has yelped, flinched, or seemed to lose her balance. If you can, take short phone videos of her walking, jumping, climbing, and getting up from a rest. A two-minute video of a cat in her own home reveals more than thirty minutes of stoic stillness on a stainless-steel exam table.

Physical examination

A veterinarian experienced with cats will watch your cat move around the exam room when possible, then carefully palpate each joint, comparing left to right for symmetry. They will gently extend and flex each hip through its range of motion, feeling for restriction, crepitus (a grinding or crunching sensation), swelling, or pain responses such as tensing, hissing, pulling away, or flicking the tail. They will also assess the muscles of the hindquarters for atrophy and check the lower spine, knees, and hocks, because hip pain often coexists with arthritis elsewhere.

X-rays

Radiographs of the pelvis are the gold standard for confirming hip dysplasia and grading its severity. Classic findings include a shallow acetabulum that does not adequately cup the femoral head, a femoral head that is misshapen or flattened, increased space between the femoral head and the socket indicating ligament laxity, bony spurs (osteophytes) around the joint edges, increased bone density under the cartilage, and thickening of the joint capsule. Many cats need to be lightly sedated for good positioning, both because positioning a painful cat with the hips extended hurts and because diagnostic-quality images depend on the cat being relaxed and symmetric. Sedation also allows a more thorough orthopedic exam at the same visit.

It is worth noting that radiographic severity does not always match how the cat feels. Some cats with dramatic X-ray changes are surprisingly comfortable, while others with relatively mild changes are in significant pain. Treatment is guided by the clinical picture, not by the films alone.

Ruling out other conditions

Several other senior cat problems can mimic the signs of hip dysplasia. Generalized arthritis of the lower spine, knees, or elbows can produce similar reluctance to jump. Hyperthyroidism can cause weight loss, behavior changes, and reduced grooming. Chronic kidney disease and diabetes can cause weakness and decreased activity. Neurological disease, including spinal cord problems, can cause back-end weakness. Because of this, most vets will run baseline bloodwork and a urinalysis as part of the workup, both to rule out coexisting problems and to confirm that medications planned for treatment will be safe.

Treatment options for feline hip dysplasia

Treatment for hip dysplasia in cats is almost always lifelong management rather than cure. The underlying joint architecture cannot be reshaped without surgery, and the goal of medical management is to control pain, reduce inflammation, preserve muscle and function, and protect quality of life. The good news is that the last few years have brought genuinely new tools to feline pain medicine, and most cats with hip dysplasia can feel substantially better with the right combination of therapies.

Frunevetmab (Solensia): a game-changer for feline joint pain

The single biggest recent advance in feline pain management is frunevetmab, marketed as Solensia. Approved by the FDA in 2022, it is a once-monthly injection given at the veterinary clinic that targets nerve growth factor (NGF), a key signaling molecule in chronic joint pain. Because it is a monoclonal antibody rather than a traditional small-molecule drug, it does not need to be processed by the liver or excreted by the kidneys in the same way pills do. This makes it a meaningful option for senior cats with kidney disease or other organ issues that would otherwise rule out long-term pain medication.

Clinical studies and real-world veterinary experience have shown striking improvements in activity, willingness to jump, grooming, and owner-reported quality of life for many cats on Solensia, often within the first few weeks. It is generally well tolerated, with mild injection-site reactions being the most common side effect. For senior cats with hip dysplasia — particularly those with concurrent kidney disease, which is common in older cats — Solensia is often the cornerstone of long-term treatment.

Nonsteroidal anti-inflammatory drugs (NSAIDs)

NSAIDs reduce inflammation and pain, and they are one of the most effective categories of medication for arthritis pain. However, cats are uniquely sensitive to NSAIDs because of how their livers process them, and chronic use must be managed carefully. In the United States, meloxicam (Metacam) is commonly used off-label in cats at low doses, and robenacoxib (Onsior) is approved for short-term use. Long-term daily NSAID therapy requires regular monitoring of kidney values and is generally avoided in cats with pre-existing kidney disease. Many vets reserve NSAIDs for flare-ups, or use them at reduced doses alongside other treatments, rather than as a stand-alone lifelong therapy.

Never give your cat ibuprofen, acetaminophen (Tylenol), naproxen, aspirin, or any other human pain reliever. Even a single dose of some of these can be fatal to cats. Use only medications prescribed by your veterinarian.

Gabapentin

Gabapentin is an oral medication originally developed for seizures and nerve pain. In cats, it is widely used for both chronic pain and anxiety and is a common component of multimodal arthritis plans. It is generally safe, can be dose-adjusted for cats with kidney disease, and comes as a capsule, liquid, or compounded treat. Side effects are usually mild, with sleepiness being most common and typically fading over the first few days. Gabapentin is particularly helpful for cats whose pain flares unpredictably, who have trouble settling at night, or who need help with the stress of vet visits.

Omega-3 fatty acids

High-quality fish oil supplements containing EPA and DHA have measurable anti-inflammatory effects in cats and can meaningfully reduce joint pain over time. They are safe, well tolerated, and easy to add to food. Many therapeutic joint diets formulated for cats already contain elevated levels of omega-3s. Discuss dosing with your veterinarian, because product concentration and quality vary widely.

Joint supplements

Supplements containing glucosamine, chondroitin sulfate, and green-lipped mussel extract support cartilage health and reduce inflammation in the joint. Evidence in cats is less robust than in dogs, but many cats appear to benefit. Cosequin and Dasuquin are commonly recommended brands formulated specifically for cats. These products are slow-acting — benefits usually build over four to eight weeks — and are most useful as long-term joint support rather than for acute pain.

Adequan (polysulfated glycosaminoglycan)

Adequan is an injectable medication that supports cartilage and reduces joint inflammation. It is approved for use in dogs and horses and is used off-label in cats. A typical protocol is a series of injections given twice weekly for several weeks, followed by maintenance dosing every few weeks. Many cats tolerate it well, and for cats who cannot use NSAIDs, it can be a useful part of a comprehensive arthritis plan.

Weight management

If your cat is overweight, weight loss is one of the highest-impact interventions available for hip dysplasia. Even a small reduction in body weight can produce a noticeable improvement in mobility and comfort. Weight loss in cats must be done carefully, however. Rapid weight loss can trigger hepatic lipidosis, a serious and sometimes fatal liver condition. A vet-supervised plan that targets a loss of no more than one to two percent of body weight per week is the safe standard. Measured meals rather than free feeding, a therapeutic weight-loss diet, and food puzzles that slow eating all help.

Physical therapy and gentle exercise

Cats are not always enthusiastic physical therapy patients, but some approaches genuinely help. Encouraging gentle play with feather wands and floor-level toys keeps the hip muscles engaged without overloading the joint. Some veterinary rehabilitation practices offer cat-specific sessions that include passive range-of-motion exercises, underwater treadmill therapy (yes, cats can do this), therapeutic ultrasound, and laser therapy. Preserving muscle mass over the hips and thighs is one of the best ways to support a painful joint.

Acupuncture and laser therapy

Veterinary acupuncture has a growing body of evidence for chronic joint pain in cats and is generally well tolerated by feline patients. Therapeutic (cold) laser therapy reduces inflammation, is painless, and can be done in short sessions. Many integrative veterinary practices now offer these as adjuncts to medical treatment, and they can be particularly useful for cats who are not good candidates for additional oral medications.

Surgical options for severe cases

Most cats with hip dysplasia are managed successfully without surgery. For a smaller number of cats — those with severe pain that does not respond to medical management, those with very advanced joint changes, or younger cats whose disease is progressing aggressively — surgery may offer better long-term comfort than continued medical therapy alone.

Femoral head and neck excision (FHO)

FHO surgery removes the head and neck of the femur, eliminating the painful bone-on-bone contact within the hip. The space fills in with scar tissue and creates a "false joint" that is functional, pain-free, and surprisingly effective in cats. Because cats are small and well-muscled, they tend to recover from FHO better than dogs do, often returning to near-normal activity within a few months. FHO is generally well within reach financially compared with replacement surgery and can be performed by many general surgeons as well as specialists.

Total hip replacement

Total hip replacement, in which the entire joint is replaced with prosthetic components, is now performed in cats by some board-certified veterinary surgeons. It restores more normal joint mechanics than FHO and is most often considered for larger cats (such as Maine Coons), for cats with severe bilateral disease, or for younger cats with aggressive progression. It is a specialty procedure with a higher cost, but outcomes in suitable candidates are excellent.

Choosing surgery

The decision to pursue surgery is individual and worth discussing carefully with both your primary veterinarian and, ideally, a board-certified veterinary surgeon. Factors that go into the decision include the cat's age and overall health, the severity of pain, response to medical management, the cat's tolerance for medication and rehabilitation, and the family's resources. For many cats, particularly seniors, medical management is the right answer for life. For others, surgery is the kindest intervention available.

Making your home hip-friendly

Medications and supplements do a great deal, but the environment your cat lives in is equally important. A few thoughtful changes can dramatically improve daily comfort and function.

Low-entry litter boxes

Swap high-sided boxes for ones with a low entry point, ideally no more than two to three inches high. If you cannot find a commercial option you like, a shallow plastic storage tub with one side cut down works beautifully. Place at least one box on every floor of the house so your cat does not have to climb stairs to use it, and consider having more boxes than you have cats — extra options reduce both physical effort and stress.

Ramps, steps, and strategic furniture

Provide gentle ways for your cat to reach the places she loves. A small set of pet steps next to the bed, a ramp to a favorite windowsill, or a footstool placed between the floor and the couch lets a cat with painful hips keep her vertical world without having to jump. Cat trees with low, wide steps between platforms are kinder than ones that require big leaps.

Soft, warm, easy-to-reach resting spots

Arthritic joints feel better with warmth and gentle support. Provide thick, well-padded beds in the spots your cat actually likes to rest. Avoid forcing her up onto a high cat bed she can no longer reach. A heated cat bed — set to a safe, gentle warmth — can be particularly comforting for senior cats with hip pain, especially in cooler months.

Traction on slippery floors

Hardwood, tile, and laminate floors are very hard for a cat with weak or painful hindquarters to navigate. The back legs can slip out from under her when she tries to push off or turn quickly. Place runners, low-pile rugs, or yoga mats along the routes your cat travels most often, especially around food, water, litter boxes, and resting areas. Keep your cat's nails trimmed so they can grip rather than slide.

Easy access to food and water

Place food and water bowls in spots your cat can reach without jumping or climbing. Slightly raised bowls — just an inch or two off the floor — can be more comfortable than ground level for cats who find lowering their head difficult, but they should not be so high that they require the cat to reach awkwardly. Multiple water stations around the house encourage drinking, which matters for both hydration and kidney health.

Gentle grooming assistance

Because cats with hip dysplasia struggle to groom their lower back and tail base, they often benefit from regular brushing in those areas. Use a soft brush or grooming glove, work in short sessions, and watch for any sign of discomfort. For long-haired breeds like Maine Coons, Persians, and Himalayans, this is not optional; mats over the hips can become painful in their own right and may require professional grooming to safely resolve.

What long-term care looks like

A diagnosis of hip dysplasia in a senior cat is not an emergency, and it is not a death sentence. It is the beginning of a long-term management relationship between you, your cat, and your veterinary team. Most cats live many comfortable years after diagnosis with the right combination of medication, environmental support, weight management, and regular monitoring.

Plan on more frequent veterinary check-ins than for a healthy cat — typically every six months for senior cats on chronic pain therapy, with bloodwork to monitor kidney and liver values, body condition checks, and re-evaluation of pain medications. Keep your own running notes on what your cat can and cannot do at home. Owner-tracked changes in jumping, grooming, litter box use, and activity are often the earliest sign that a treatment plan needs adjusting.

Watch in particular for signs that pain is escalating: new reluctance to walk at all, vocalization when moving, refusal to eat, hiding for prolonged periods, or new inappropriate elimination. These signs warrant a prompt veterinary visit, not a wait-and-see approach. With current treatments — particularly with Solensia and gabapentin available as kidney-friendly options — there is almost always something more that can be done to improve a cat's comfort.

When to call the vet

Schedule a non-urgent veterinary appointment within the next week or two if your senior cat shows any of these signs:

• New reluctance or new difficulty jumping up or down from familiar surfaces
• A bunny-hopping gait, particularly when moving quickly or going up stairs
• Stiffness after rest that loosens up with movement
• Changes in grooming, especially matted fur over the lower back, hips, or tail base
• New litter box accidents, eliminating just outside the box, or eliminating with the back end overhanging the edge
• Reduced play, climbing, or interest in vertical space
• Migration to lower, easier resting spots
• Flinching, swatting, or hissing when touched around the hips or lower back
• Visible muscle loss over the hips and thighs
• An abnormal sitting or lying posture, such as one leg sticking out to the side

Call your veterinarian sooner — within a day or two — if your cat shows any of the following:

• Sudden, complete reluctance to bear weight on a back leg
• Vocalization when moving or being touched
• Loss of appetite combined with mobility changes
• Hiding for prolonged periods, particularly with reduced grooming or eating
• A clearly unsteady or weak back end that was not present before
• Any new neurological signs, such as dragging a paw, knuckling over, or loss of coordination

Sudden, severe back-end weakness or paralysis in a cat is not typical of hip dysplasia and can indicate a more serious problem such as a saddle thrombus (a blood clot) or spinal disease — both of which are urgent. When in doubt, call.

Caring for a senior cat with hip dysplasia

Learning that your cat has hip dysplasia can feel both clarifying and heavy. There is relief in finally having a name for the changes you have been quietly worrying about, and there is sadness in knowing that the joint disease is permanent. Both feelings are appropriate, and both belong in this conversation.

What is also true, and worth holding onto, is that hip dysplasia in cats is one of the most treatable orthopedic conditions of the senior years. Modern feline pain medicine — particularly the arrival of Solensia — has shifted what is possible for these cats more in the last several years than in the previous several decades combined. Most senior cats with hip dysplasia, given a thoughtful combination of medication, weight management, environmental support, and regular veterinary care, go on to be comfortable, engaged, affectionate companions for a long time.

The day-to-day picture often improves more quickly than owners expect, because the chronic, low-grade pain they had subconsciously normalized finally lifts. Cats start jumping to places they had abandoned. They start grooming areas they had been ignoring. They start playing again, settling more easily at night, and meeting you at the door in the morning. None of this looks like a cure, because nothing has cured the underlying joint. But the quality of life it represents is real, and it is precisely what good senior cat care is meant to deliver.

Notice the small things. Keep her weight where it belongs. Make the litter box, food bowls, and resting spots easy to reach. Brush the hard-to-reach places yourself. Keep the follow-up appointments. Stay alert for changes. And remember that "just getting old" is, more often than not, a diagnosis worth questioning — because behind it, in so many cats, is a quietly painful joint that can finally be made comfortable.

This article provides general educational information about hip dysplasia in cats. It is not a substitute for individualized veterinary advice. The right diagnostic workup, medications, surgical options, and long-term plan all depend on the individual cat — her breed, body condition, severity of disease, coexisting conditions such as kidney or liver disease, and family resources. Decisions about pain medication, supplements, weight loss programs, and surgery should always be guided by a veterinarian who can examine your cat, review imaging and bloodwork, and tailor a plan to her specific needs. Never give your cat human pain medications, including ibuprofen, acetaminophen, naproxen, or aspirin; even a single dose of some of these can be fatal to cats. If your cat develops sudden, severe back-end weakness, paralysis, vocalization with movement, loss of appetite combined with mobility changes, or any new neurological signs, seek prompt veterinary care rather than waiting for a routine appointment.
