My thoughts also. If the cornea is scratched, that can be very painful. Tow of my cats were playing, got a bit rough, and Vita scratched Sparkle's eye. Of course this heppened late on a Saturday, requiring a trip to the Emergency Vet (along with a bank roll of cash.) Came back with 3 eye drops, one to relieve pain, one to keep it dilated and one to . . . do something else. Can't recall, this was 2 years ago. Anyway, had to go in to regular vet 10 days later to ensure it was all healed up.

Cats don't show signs of being sick, but Sparkle was obviously feeling lousy. She had the eye almost closed, and just kept laying down. Didn't paw at it or anything like that.
