My fiances cat had kittens and she let all of them die but I was able to take one in. Lately this little guys anus is swollen and a little blood comes out when it poops and its almost yellow. I figured it was from straining or something. Its only like a week old if that. I will be getting it seen real soon but I don't like to wait and take chances. I think its loosing weight so I'll be feeding it every two hours instead of four. I read somewhere else someone was having the same problem but theirs was sneezing and all. Mine is just the swelling and alittke blood besides that he seems ok
