I have been noticing more and more when I pet my female cat (Bunnie) around the neck there are scabs there. I think her brother is fighting rough with her when hubby and I are at work all day. He's had a few scabs and had a tiny patch of fur missing from the top of his head, too. They are so lovey dovey sometimes with eachother, she loves to give him a bath and they snuggle up together sometimes. I don't know what goes on while we're at work???? Anybody else experience this and have any suggestions?
