Ahh I don't know what's wrong with him but I saw it yesturday afternoon his eye was like blood red. Not the whole thing. But I don't know what's wrong he seems fine still scared of everything just now his eye is red? Can you help tell me what could be wrong.

The vet can tell you. Why don't you take him there?

Maybe a blood vessel broke... whatever that could be, see a vet to be sure that your cat receives the best treatment.
