I got an email from my friend who said she had a cat, Luna, who had an eye ulcer her entire life that never bothered her. So, I'm just going to keep using the eye ointment for it. It doesn't seem to bother him. What DOES bother him is the weird skin condition under his chin (not kitty acne) on his breastbone. The vet gave me anti-itch cream to put on it.
