My cat got a bit rambunctious when playing with the kittens, and one of them scratched his eye a bit. This was almost 2 weeks ago. He never showed any discomfort (no squinting/unwillingness to open eye, no discharge, no fear of anything like that) or even awareness that he was hurt, so we didn't take him to the vet. I feel like it should be healed by now, and I think it is. But its still very red like there's dried blood on it or something? Im just wanting to know if this is normal at all, should I be concerned? These are the best pictures I could get of it. He keeps just trying to headbutt my hands and phone.
