My sphynx seems to scratch her face and her neck way too much, to the point of irritating it. She always have little scratches on her, which seem to make her want to scratch even more. How can I make her stop? I bathe her often, clean her ears, etc.. so I'm not sure why she does it. Also, is there some kind of safe lotion that I can put on her that will help soothe these parts so that she doesn't feel the need to scratch?
