For a while a couple months ago I was feeding my cat canned tuna and salmon. I didn't realize that it wasn't healthy for him. I stopped and now feed him ONLY cat food. Last night he had a fever, now his mid-back is sore to touch. he crouches when he walks. Nothing is wrong with his back legs. It might be from a fall or something. has anyone had a cat with this disease? if so, what are the symptoms??
That disease or not, he needs to go to the vet soon!
