Cleve & Teddy
Junior Guinea Pig
So Cleveland who is maybe like 8 months old now every once in a while has something poke out of his butt. it almost looks like some sort of skin? It is round and big and he pushes it out through his butt and then it goes back in. I thought maybe it was his grease gland or something marking his territory because it usually happens when he is purring or trying to intimidate teddy. But I can't even find his grease gland, i know it's supposed to be where a tail would be if he had one, but I can't find it on him. Anyways, does anyone know what this is/is it normal? Sorry for the icky question.
