It looks like someone has been fighting and he's feeling very sorry for himself, he has a couple of holes in his ears and scratches on his forehead. I'm not going to say "Oh no next doors cats have attacked Junior" as I'm more inclined to believe that Junior would cause trouble, or at least not walk away from it. I do hope we don't have another unneutered male on the prowl here as that would be a nightmare, especially with the young boys. This is the second time Junior has got himself in trouble, but it must be a year since the last time so hopefully not connected.
Junior has not eaten this morning so I guess he's hurting. I'll have to keep an eye on him now for infection and abscesses. Happy days!
