Brooklyn, a year old cat, has been giving off this red discharge from his left eye. The eye doesn't look swollen, and he doesn't seem bothered by it. We bought "eye wipes" specially made for cats and wipe his eye about every other day. What could this be? I know we'll have to take him to the vet--but what should I be ready to hear it could be? I'll try to get a picture if I can. We just wiped his eye so it wouldn't be a good depiction of the problem.
