Hello ,I adopted a Himalayan about 2 months ago,His name is Catfish, (his name when I got him ) lol.He is Siamese color.and weighs 10 and a half pounds. He has been neutered and declawed on all 4 paws. He had a cold in his eye when I got him. but have had him to the vet 3 times scents then for respitory infection and cold in his eye again. Now he acts like he is so stiff he cant hardly get around. I have checked his feet and legs and cant find anything wrong. Then thought with him being so heavy that when he jumps off of things he may have just stoved his self up . but he has been like this for 3 days. he is still eating and drinking and going to the litter box as usual.Taking him back the vet Monday. Are these kind of cats prone to illness? You could tell he had been mistreated in the past, he would scurry out of the room when you entered or would dart under the couch at just a little noise. For the past 3 days he acts like nothing scares him and he lays on the couch up against me and lays their except to go eat and drink and go to the litter box. I do have a kitten Mitts that is really rowdy, I thought maybe he is doing that to get away from her. Would really love all the input I can get.
