Our cat has been limping for a few days. We looked very carefully at his leg and couldn't find any visible injuries or swellings. We thought he might have landed heavily or sprained it. We kept him in for a day in the hope that some enforced rest would help. It seemed to be improving but tonight he's limping as badly as ever. Obviously the wait and hope approach hasn't worked so we will take him to the vet tomorrow. I'm just wondering whether anyone has any suggestions about what the cause might be?
