Hi, so my wonderful cat Lovey who was born in 1986 has been in wonderful health. Although he is skinny he eats like a pig and he's very sweet. I've noticed he can't see as well as he used to but I've just figured it's old age. Well tonight when I went to give him a can of wet food he looked up at me and his eye seemed very red. Like there is blood in it/ behind it. I don't know how to explain. But his whole left eye looks this way. I assure you he is a very happy cat, he roams freely around the house and eats so much! He even sleeps with me every night. He is very sweet and I would hate for anything to be wrong. Please help!!
