It's so tiny I can't get a pic of it, but I noticed that the outside toe of her right hind foot is red and sort of crusted, like a scab. Just noticed yesterday, what should I do? I'd try antibiotic cream, but I think she'll lick it off, and I don't want to get her sick, it's no supposed to be eaten. Should I make her walk through hydrogen peroxide, or rubbing alcohol, or iodine? She's a lovely broken blue, I really want to keep her.
