Arthritis in Cats: Hidden Signs & How to Help
Start here
Arthritis (degenerative joint disease) is very common in older cats, yet often missed because cats hide pain. Instead of limping, arthritic cats usually show subtle changes: jumping less, hesitating on stairs, sleeping more, grooming poorly, and sometimes missing the litter box. It can't be cured, but pain relief, joint support, weight management and simple home changes can dramatically improve comfort.

Why arthritis is so easy to miss
Most cat owners expect arthritis to look like a limp. In cats, it rarely does. Cats are masters at hiding discomfort, and because both sides usually wear down together, there's no obvious "good leg" to favor. Instead the signs are quiet changes in what your cat chooses to do — and they're easy to write off as "just getting old."
That's a costly assumption, because arthritis is genuinely common in senior cats and the pain is real and treatable. Recognizing the subtle signs is the whole game. Our senior care mindset applies to cats too: slowing down is not automatically "normal aging."
The subtle signs to watch for
Look for changes in movement, habits and grooming rather than an obvious limp:
- Jumping less or no longer getting onto favorite high spots
- Hesitating, or taking the stairs one at a time
- Sleeping more and playing less
- A messy or matted coat, especially over the back and hips, because grooming hurts
- Overgrooming a specific joint, or the opposite
- Litter-box accidents — climbing into a high-sided box can be too painful
- Irritability when touched or picked up, and hiding more
Practical take: if your senior cat has stopped jumping onto the counter or bed it used to reach easily, treat that as a possible pain signal, not just aging.
Diagnosis
Your vet diagnoses arthritis through a combination of your observations, a physical exam checking the joints for pain and reduced range of motion, and sometimes X-rays. Interestingly, the severity of changes on an X-ray doesn't always match how much pain a cat feels — so your descriptions of behavior at home are a crucial part of the picture. Your vet will also rule out other conditions that can look similar, since older cats often have more than one issue at once. A history of how your cat's activity has changed over months is far more useful than a single exam-room snapshot.
Treatment and managing pain
Management combines medical treatment with practical changes, tailored by your vet:
- Pain relief: vets have cat-specific options, including an injectable monoclonal antibody treatment developed for feline arthritis pain, and certain anti-inflammatories used carefully. Never give human pain medications — many, including ibuprofen and acetaminophen, are toxic to cats.
- Weight management: extra weight loads the joints, so reaching a healthy weight is one of the most effective steps.
- Joint supplements and diets (such as those with omega-3 fatty acids) that some cats benefit from.
- Other therapies like physical rehab as advised.
Home changes and tracking progress
Small adjustments make daily life easier: a litter box with a low entry, ramps or steps to favorite perches, soft warm bedding, food and water at floor level, and easy access to sunny resting spots. Because arthritis pain is gradual and cats hide it, tracking is especially valuable here — note how often your cat jumps, plays, or has litter-box accidents, and its weight. That record helps you and your vet judge whether a pain treatment is actually working, since improvement shows up as your cat doing more of what it enjoys, not as a number on a test.

Frequently asked questions
How do I know if my cat has arthritis?
Watch for subtle changes rather than limping: jumping less, hesitating on stairs, sleeping more, a messy coat from reduced grooming, litter-box accidents, and irritability when touched. These are easy to mistake for normal aging. If you notice them in an older cat, ask your vet to check for joint pain.
What can I give my cat for arthritis pain?
Only give what your vet prescribes. There are cat-specific options, including an injectable treatment developed for feline arthritis pain and certain carefully used anti-inflammatories. Never give human pain relievers like ibuprofen or acetaminophen, which are toxic to cats even in small amounts.
Is arthritis common in cats?
Yes, it's very common in older cats, though frequently underdiagnosed because cats hide pain so well and rarely limp. Many senior cats have joint changes even when they seem fine. Because it's both common and treatable, it's worth raising with your vet as your cat ages.
Can weight loss help a cat with arthritis?
Yes. Extra weight places more stress on already sore joints, so reaching and maintaining a healthy weight is one of the most effective ways to reduce arthritis pain. Weight loss should be gradual and vet-guided, since crash dieting is dangerous for cats.
What home changes help an arthritic cat?
Provide a litter box with a low entry, ramps or steps to favorite perches, soft warm bedding, and food and water at an easy height. These reduce the painful jumping and climbing that daily life demands. Combined with veterinary pain management, they make a real difference in comfort.
