Q. My 5 yr old cat has a swollen back paw-no apparent injury. He is not limping, but the swelling is there - should a vet be called?
A. Yes, I would recommend a vet check up. I am sure the paw is uncomfortable and early medications will ease the pain and prevent the swelling to get worse. With regards to the cause, it could be that she has some kind of infection secondary to a scratch or bite, or some kind of soft tissue injury ( although the swelling is normally not marked and the localisation is unusual ). I doubt is anything more serious like a fracture otherways limping would be really evident.
