Are there things I can do at home to help my cat avoid skin issues?

There are. One of the big things is keeping your cat nice and lean. How about that? Most people didn't think this was going to be a fat talk. Cats are great groomers, as long as they can reach the spots to groom. If they groom, they tend to keep their skin nice and healthy. But when they get overweight, the hair, especially down the back, over their tailhead, they can't reach it. And if they can't reach it, it builds up and mats up, which leads to some really severe and nasty skin issues. Keeping your cat combed, if they'll allow it, would be great. Bathing cats, if your cat will allow it, it's fabulous. That's the rare cat who likes to have a bath, and I sure don't want you scratched or bitten trying to bathe your cat if they don't like it. Once again, cats are such good groomers that they don't need bathing as frequently as dogs. Also, keep fleas under control.
