Arthritis in Cats: Signs, Diagnosis and Treatment

Written by Cath Lyon, Copywriter. Reviewed by Dr. Linda Simon MVB MRCVS, Team Vet.

Arthritis in cats is common, painful and easy to miss. A cat may not limp or cry. More often, the first clue is a small change in daily behavior: pausing before a jump, sleeping in a new place, using the stairs less, missing the litter box or grooming the back and hips less thoroughly.

These changes deserve attention rather than being dismissed as normal aging. Arthritis cannot usually be cured, but early veterinary assessment, pain control, weight management and practical changes at home can protect comfort and quality of life.

What is arthritis in cats?

Arthritis, often called osteoarthritis or degenerative joint disease, develops when a joint and the tissues around it change over time. Cartilage no longer cushions movement as effectively, the joint can become inflamed and movement may hurt. The hips, knees, elbows, spine and other joints may be affected, and a cat can have changes in more than one area.

Age is an important risk factor, but arthritis is not limited to senior cats. Earlier injury, joint instability, developmental conditions and abnormal joint shape may contribute. Extra body weight can also increase the mechanical load a painful cat carries.

Published feline guidance emphasizes that chronic pain assessment should include what the owner sees at home, because a cat's movement in a clinic may not reveal every limitation. The FelineVMA and AAHA pain management guidance describes an integrated approach instead of relying on one observation or one treatment.

Signs of arthritis in cats

Compare your cat with their own normal routine. A phone video of walking, climbing, jumping or using the litter box can give the veterinarian useful context. Look for patterns such as:

• Hesitating before jumping up or down
• Choosing lower surfaces or climbing in stages
• Stiffness after sleep or a shortened stride
• Less play, exploration or interaction
• Difficulty entering a high-sided litter box
• Eliminating beside the box when entry hurts
• Reduced grooming, especially over the back and hindquarters
• Overgrooming a painful area
• Irritability or avoiding touch
• Sleeping more or hiding in accessible locations
• Muscle loss, weight change or reduced appetite

Limping can occur, but its absence does not rule out joint pain. Cats naturally conceal vulnerability, and changes may develop so gradually that the household adapts without noticing.

What cat breeds are more prone to arthritis?

Any cat can develop arthritis. Breeds associated with inherited joint or cartilage conditions may face additional risk. Maine Coons, Persians and Siamese may be affected by hip dysplasia, while Scottish Folds have a cartilage mutation that can cause serious skeletal disease. Breed changes risk, not certainty, so behavior and veterinary findings matter more than a label.

How is arthritis diagnosed in cats?

A veterinarian combines the history, home observations and a physical examination. They may watch the cat walk, assess muscle condition and gently evaluate the range of motion and response around individual joints. Because cats can become still or tense at a clinic, videos from familiar surroundings can be especially valuable.

X-rays may show joint changes and help rule out other problems, but image findings and pain do not always match perfectly. Some cats with substantial radiographic change show subtle behavior differences, while others are painful before the image looks dramatic. Blood or urine testing may be advised before medication or when another illness could explain the signs.

How is arthritis treated in cats?

Treatment is individualized and often uses several tools together. A veterinarian may discuss prescription pain relief, anti-inflammatory treatment, weight management, rehabilitation, environmental changes and ongoing reassessment. The safest choice depends on age, kidney and liver health, other diseases, current medication and how reliably treatment can be given.

Never give a cat human pain medicine. Acetaminophen is highly toxic to cats, and human or canine anti-inflammatory drugs can cause life-threatening harm. Do not use leftover medication from another animal. If pain treatment seems ineffective or causes vomiting, diarrhea, appetite loss, unusual thirst, weakness or another change, contact the prescribing clinic promptly.

Medication is not the only useful change. Your veterinarian may recommend a calorie plan for gradual weight loss if needed, controlled low-impact activity, physical rehabilitation or a nutrition strategy. Evidence and suitability differ among supplements, so review ingredients and doses with the veterinarian rather than stacking products.

Make the home easier to navigate

• Place wide, stable steps or a textured ramp beside favorite furniture.
• Use a low-entry litter box while keeping enough substrate for normal digging.
• Provide a box on every level the cat uses.
• Keep food, water, resting areas and litter within easy routes.
• Add nonslip runners to slick floors.
• Offer warm, supportive beds in quiet locations.
• Raise bowls only if the individual cat finds that position easier.
• Keep nails at a safe length and ask for help if trimming is stressful.

Avoid redesigning everything in one day. Familiarity matters to cats. Introduce one safe option, observe whether the cat uses it and keep an accessible alternative.

Can you prevent arthritis in cats?

Not every case is preventable. You can still reduce avoidable strain by maintaining a healthy body condition, providing regular play that fits the cat's abilities, preventing falls and treating injuries promptly. Stable steps can reduce repeated large impacts while preserving access to favorite spaces.

Regular examinations create a baseline for weight, muscle and movement. Bring up small changes before the annual visit if they persist. Earlier assessment may identify dental disease, neurologic problems, urinary disease or another condition that can resemble a mobility problem.

When to contact a veterinarian urgently

Seek prompt care for sudden inability to stand, dragging a limb, a cold or painful paw, severe distress, collapse, breathing difficulty, major trauma or loss of bladder control. A gradual decline also needs an appointment. Arthritis is common, but a new mobility change should not be diagnosed at home.

FAQs

At what age do cats get arthritis?

Risk increases with age, but younger cats can be affected after injury or because of developmental and inherited joint problems.

Can a cat have arthritis without limping?

Yes. Changes in jumping, grooming, litter box use, sleep and interaction are often more noticeable than a limp.

Can I give my cat aspirin or ibuprofen?

No. Human pain medications can be dangerous or fatal to cats. Use only medication prescribed specifically for that cat by a veterinarian.

Does arthritis mean a cat must stop jumping?

Not automatically. Provide lower, stable routes and ask the veterinarian how much activity suits the individual cat.
