Okay, so the kittens started opening their eyes about 5 days ago, Pandas eyes were the first to fully open, for 2 days they were open and clear. The next day, crust had formed over one eye, I used sterilized cotton guaze and cleaned it, like the sites say, and yesterday I noticed her other eye has crusted over! And then I pick up Sadie, and her eye has crust too! Could this be an infection? It's not green crust or anything, it's kind of a yellow-brown color. Should I just keep on doing what I have been or try something else? At petco they have an eye wash, but it contains a small amount of boric acid and I have heard that it can blind them. Should I be as worried as I am about it, or will it go away if I continue cleaning it everyday?
