So, I got to thinking about the last batch of little ones in this house (about 3 years ago) and I realized that one of them, now a full grown kitty, also had recurrent eye infections as a kitten. I tried to remember what the vet said, and I remember asking if it was okay to use the arithomycin. I don't remember his advice, but I do remember using it. The tube that I have is about 4 years old, so not very potent at all. I used a tiny dab on Butty's eyes last night 2x, and a dab this morning and his eyes are open wide and he is playing with his siblings! Woo Hoo! Now, I know you are going to advise against this, but I was getting very concerned and couldn't afford the vet. I figured something that I KNOW is for conjunctivitis in a very mild potency is better than letting the poor little kitten suffer. So while you probably won't recommend it for other new babies, it has had some success with Butty.
