Do any of you have a kitty with arthritis? The reason I ask is because Max is now limping quite badly and is favouring one of his front legs. It just started yesterday but this morning it's worse. I've examined his leg and paw but can't see anything. I will call the vet but was hoping for some information here if you have any. It seems to get a bit better the more he walks; it's only when he's been sitting for a period of time which leads me to believe that it's a joint problem.

How is arthritis diagnosed? Anyone know?

Thanks.
