I forgot to ask the vet while I was on the phone with him, but it's prolapsed and terribly dried out, I've only had him for about a week when someone I knew was giving him away, so my boyfriend and I were eager to get him since we have two females and wanted to breed them when they had gotten old enough to. When I went to go pick him up it shocked me of how he had treated the poor thing. It had no lighting at all, no water, no kind of heat source, was pretty emaciated and wasn't lively in the least. In the past week he's obviously started to gain some weight and is considerably more active, but i noticed the shriveled to nothing member about three days ago and called the vet to get him in as soon as I can.
Thanks for the help!
