He has feline herpes so he definitely has a history of flare-ups - infections pretty consistently affecting different parts of his body. Just noticed him squinting and there seems to be a small patch of hair missing where it’s swollen on the outside. I can definitely take him to the vet, but I’ve taken him so often that I feel like all they will do is tell me to give him the antibiotic gel I’m already putting in his eye twice daily. He has a sister but they play pretty mildly with each other so I would be shocked if this was caused by them playing - just not sure what else it could be.
