Cat arthritis: the signs every owner misses (and what actually helps)

If you asked most cat owners whether their cat has arthritis, most would say no. And they'd probably be wrong.
Studies consistently show that over 90% of cats over the age of 10 have some degree of joint degeneration visible on x-ray. In cats over 14, that figure climbs even higher. And yet arthritis remains one of the most underdiagnosed conditions in domestic cats.
The reason comes down to something that makes cats extraordinary, and in this case, also makes caring for them harder. Cats are masters at hiding pain.
Why cats hide arthritis
In the wild, showing weakness is dangerous. A cat that limps is a target. So cats evolved to mask discomfort, and they do it extraordinarily well.
Unlike dogs, cats don't typically limp when they have arthritis. They adapt. They stop doing the things that hurt. They change their habits so gradually that owners often don't notice until the change is significant.
By the time most cat owners realise something is wrong, their cat has been managing pain for months.
The signs most owners miss
Here's what to look for, particularly in cats over seven years old.
Changes in jumping behaviour
Your cat stops jumping to the top of the cat tree. They hesitate at the edge of the couch before coming up. They take the route that requires less height. This is often the first sign and the one owners are most likely to dismiss as "just getting older."
Stiffness after rest
Watch your cat when they first wake up. Do they walk stiffly for a minute or two before moving normally? This is a classic sign of joint inflammation and one that's easy to miss if you're not specifically watching for it.
Changes in grooming
Cats with arthritis often can't reach certain parts of their body, particularly their lower back and the base of their tail. You might notice matting in these areas, or that your cat seems to have stopped grooming as thoroughly as they used to.
Litter tray changes
A cat in joint pain may find it difficult to climb in and out of a high-sided litter tray. They might avoid the tray, start missing the edges, or seem uncomfortable in the posture required to go.
Behaviour changes
Cats in pain often become more irritable. They may pull away when touched in certain areas, react badly to being picked up, or seem generally grumpier than usual. This is frequently dismissed as personality when it's actually communication.
Sleeping more, engaging less
Increased sleep and reduced interest in play or interaction can both signal pain. This often gets written off as "just slowing down with age" when it may be something that deserves active support.
What actually helps
Arthritis in cats can't be reversed. But it can be slowed down significantly, and your cat's quality of life can be maintained much longer with the right support started early.
Weight management is one of the most impactful things you can do. Every extra gram puts more pressure on already-stressed joints.
Environmental modifications help enormously. Ramps or steps to favourite spots, lower-sided litter trays, heated beds in favourite sleeping areas.
Joint supplementation with research-backed ingredients can make a significant difference. The ingredients worth looking for in a quality feline joint supplement:
Type II collagen supports cartilage integrity and has good evidence in feline studies for reducing joint discomfort.
New Zealand Green Lipped Mussel contains a unique combination of omega fatty acids with anti-inflammatory properties specific to joint tissue.
Omega-3 fatty acids (EPA and DHA specifically, not just general omega-3) support joint membrane health and reduce inflammation.
And ours containts all three:
The important caveat is that not all supplements are equal. Many cat supplements use ingredients studied in humans or dogs, at doses not calibrated for feline physiology. What works for humans doesn't always translate.
When to see your vet
If you've noticed any of the signs above, it's worth a conversation with your vet. X-rays can confirm joint changes and rule out other causes. And having a baseline now means you'll be able to track changes over time.
Arthritis in cats is manageable. But only if you catch it.
