If your cat has stopped jumping, grooms less, or seems grumpy when you pick them up, it may be more than a normal part of aging. Cat arthritis symptoms are often quiet behavior changes, not an obvious limp. A veterinary evaluation can help identify joint pain and rule out other causes.
Cats are remarkably good at hiding discomfort. Instead of showing a clear limp, they may gradually adjust their routines until the things that hurt are simply no longer part of their day. Noticing those small changes is an important way to care for your animal companion.
What is arthritis, and why can it be hard to spot in cats?
Arthritis, also called osteoarthritis or degenerative joint disease, is a long-term condition involving changes to the joints and surrounding tissues. It can cause stiffness and pain that make everyday movement (such as climbing, jumping, or getting into a litter box) more difficult.
Feline arthritis is common, especially in older cats. Studies have found X-ray evidence of joint changes in about 90% of cats over 12 in some study groups. That figure refers to radiographic changes, though; it does not mean every cat has noticeable pain or needs the same treatment.
Cats often show different signs from dogs. A limp may be absent or hard to notice. Instead, a cat may quietly stop jumping to a favorite place or spend more time resting. Those gradual changes can be mistaken for personality or “slowing down,” and joint pain can go unrecognized for a long time.
Which cat arthritis symptoms should you watch for?
Look for changes from your cat’s usual habits. One sign alone does not confirm arthritis, but a pattern is worth discussing with your veterinarian.
-
Hesitating before a jump or no longer jumping: Your cat may pause, choose a lower route, or stop visiting a favorite perch.
-
Sleeping in lower places: A bed or chair may become easier to reach than a windowsill or cat tree.
-
Litter box struggles: Your cat may avoid a high-sided box, take longer to climb in, or have accidents nearby. This can be mistaken for a behavior problem, but stepping over a tall edge may be uncomfortable.
-
Less grooming, especially around the lower back and hips: Stiffness can make it harder to turn and reach certain areas. You might notice an unkempt coat or mats.
-
Irritability when touched or picked up: A cat who once welcomed handling may flinch, move away, or vocalize when a sore area is touched.
-
Reduced activity: Your cat may play less, move around the home less, or spend more time resting.
-
Changes in social habits: Some cats withdraw, become less tolerant of other pets, or seem restless when settling down.

These signs can also have causes other than arthritis. Litter box changes, in particular, can point to urinary or other health concerns. Arrange a veterinary check rather than assuming the cause is behavioral.
How do veterinarians assess arthritis in cats?
Diagnosis usually starts with what you have observed at home. Your veterinarian may ask when the changes began, which movements your cat avoids, and whether their appetite, grooming, or litter box routine has changed. Short videos of your cat walking, using steps, or attempting a familiar jump can help show movement in a more natural setting.
A physical examination may include watching your cat move and gently assessing the joints, range of motion, and muscle condition. Cats may be tense or reluctant during an exam, so your at-home observations are valuable.
X-rays can help show changes in the joints and support a diagnosis. However, X-ray findings do not always match how much pain a cat experiences. Your veterinarian considers imaging alongside your cat’s history and examination.
Bloodwork does not diagnose arthritis. It can, however, help check for other health problems that may affect mobility and provide important information before medication is considered.
Why might a cat health test be recommended before pain medication?
Older cats may have kidney, liver, or other health changes that influence which treatments are appropriate. A senior-cat health assessment can help your veterinarian understand your cat’s overall health before starting long-term medication.
Depending on your cat’s needs, testing may include:
-
CBC (complete blood count): Measures red blood cells, white blood cells, and platelets.
-
Blood chemistry: Measures values related to organs such as the kidneys and liver. Creatinine is a waste product measured in blood that can help assess kidney function; it is interpreted alongside other findings.
-
Urinalysis: Checks urine concentration and other features that add context to kidney health and hydration.
-
Additional screening: Your veterinarian may recommend other tests, such as thyroid testing or blood pressure measurement, based on your cat’s age, history, and symptoms.
This matters because cats have species-specific medication considerations, and not every pain reliever is suitable for every cat. Some cats may be candidates for a veterinarian-prescribed nonsteroidal anti-inflammatory drug (NSAID), a medicine that reduces pain and inflammation. A veterinarian should weigh the potential benefits and risks, review organ function, and decide what monitoring is needed. Never give your cat a human pain reliever or start, stop, or adjust medication without veterinary guidance.
If your veterinarian is considering long-term medication, ask whether a senior cat panel and urinalysis are appropriate first. An at-home cat blood test or senior cat bloodwork may offer a convenient way to gather some of the information your veterinarian needs. Lab testing is one part of the picture: it does not confirm arthritis or replace an exam, X-rays, or urgent veterinary care.

What can you change at home to make movement easier?
A few practical adjustments can help your cat reach favorite places and daily essentials with less effort:
- Add stable steps or a ramp to a bed, sofa, or preferred perch.
- Choose a litter box with a low entry and place it somewhere easy to reach.
- Provide soft, supportive bedding in a warm, accessible spot.
- Keep food, water, and litter on the same level when possible.
- Use nonslip rugs where your cat walks on smooth floors.
Weight management can also matter. Extra weight puts more stress on joints, while unexplained weight loss can signal another health issue. Ask your veterinarian for a suitable nutrition and activity plan. Gentle, regular play may help maintain movement, but follow your veterinarian’s advice and let your cat set the pace.
What treatments might your veterinarian discuss?
There is no one-size-fits-all plan. Depending on your cat’s health and the severity of their discomfort, your veterinarian may discuss pain-relief medication, other pain-management approaches, weight support, controlled activity, or rehabilitation. Some cats may be candidates for a monoclonal antibody treatment that targets a pain pathway. Your veterinarian can explain which options are available and suitable for your cat.
Keep track of changes in jumping, grooming, activity, litter box use, and tolerance for handling. These everyday details can help you and your veterinary team understand how your cat is doing and whether the plan needs to change.

When should you contact a veterinarian?
Book an appointment if your cat is repeatedly avoiding jumps, grooming less, struggling with the litter box, or becoming less active or more irritable. Seek prompt veterinary care for sudden severe pain, an inability to stand or walk, or a sudden major change in behavior. If your cat is straining to urinate or cannot pass urine, contact a veterinarian urgently.
Your cat does not need to limp for their comfort to deserve attention. A change in routine may be the first visible clue that something is wrong. With veterinary diagnostics, thoughtful pain management, and a few home adjustments, many cats can move more comfortably and keep enjoying the places and routines they love.
