My gorgeous kitten (4 months) loves play fighting with my middle cat (3 years), there is never any malice etc and they are supervised,mainly because of the size of the middle one, he is MASSIVE, but, i notice earlier that the kitten has a scratch on his eye, it touchs the corner of the eye missing the eye by a sheer milimeter, he doesn't seem in any discomfort, his eye looks bright and the scratch isn't bleeding, should I just bathe it and keep an eye on it?
