I'm quite worried about my cat. He has a wound on his cheek. I. Sent see it very well because of my vision problems but I'm close inspection it doesn't appear deep. It's not bleeding, doesn't look like it's bled either, just looks red. There's hardly any hair where the wound is. How do I clean it? Do I need to make a vets appointment? I think it may have been my other cat. Recently I don't know if it's fighting or rough playing but they will chase each other about the house and it usually ends when one of them seeks refuge on top of the door. They do tend to argue over who hits in the basket at the very top of the cat tree. Not often, but it does happen. Sorry for this ramble. They've never had any scratch or injury and I'm trying not to panic.
