Q. My 13 yr old male indoor cat displays tenderness to touch in his sides/haunches and it is increasing. Recently put him on diet for arthritis.

A. While tenderness in the back and hips can indicate arthritis pain, it can also sometimes indicate pain internally such as stomach or other organ issues. Cats and other pets will often stiffen their backs to protect the abdomen when in pain. If the pain continues or your cat is still in pain with arthritis treatment it is best to schedule a checkup with your vet to make sure there is not another source for the issue.
