Poor guy is not *that* bothered but buttholes should not be red, agreed?
He's pressed is bottom on the floor and scooted just a little bit about twice a day. When he goes out in the snow you'd think that'd be the best time to do that, but he doesn't. He just carries on rolling in the snow and rubbing on he fence like the silly joy clown he is.
I will take him to the vet, but any experience in inflamed assholes would be appreciated. (SO hard not to make jokes here.)
