I have a 2 1/2 year old male tabby cat which I adopted from the local SPCA. The friendliest cat ever, he's always been so full of life, gorgeous big coat and fat! Since January we've noticed that the cat has dramatically been losing weight and losing his hair in places, at first we put it down to hunting and breeding season( as my cat goes outside at night) and there is a lot of other stray cats around the area we presumed he might have been getting in some fights. But now we are worried as the weight decrease is to much. Has anybody else seen this in their cats or can you give me any information? I've brought him to the vet yesterday and the vet took bloods for fiv :-( I really hope it's not
