I have seen this happen time and time again with my dog Scraps. He is a Maltese and has long hair. Every now and then he gets a hair in his eye and it looks horrible. I flush it with contact lens saline solution and it usually flushes the hair out. His eye is usually red for awhile but it all clears up and I can see his bright, shiny eyes again. I'm guessing that is what it was but if you are still concerned, or it recurrs, call you vet.Okay this is a weird cat. I just looked at his eyes again and they are normal...
