Sodapops, thank you so much for your speedy reply. :rose
I will dig around some more, but I'm certain that's what it was: bore glue. I am just shocked that so much of it built up so fast. I play with them every day and spend a lot of time petting them. I have no doubt that this wasn't there last night. Is it typical for it to build up so fast?
Ginger was pestering him terribly, so I decided to take care of it tonight. I found an excellent post on "spot cleaning" and decided to do that. I put him in the sink like I was going to give him a bath (towel on the bottom of the sink, etc.) and applied a teeny bit of water to the area and a big dollop of baby shampoo. I massaged it into the area and the baby shampoo started to break up the worst of it immediately. After several minutes of this, there was still some on there. I thought about cutting it off (this was before I read your reply), but decided to try one more thing.
I know from experience that cheapo conditioner will remove oil from hair. I use it to remove coconut oil from my long hair before shampooing. So I applied a tiny amount of V05 Strawberries & Cream conditioner to his little butt. I massaged that into the hair and it removed almost every trace of the boar glue. I rinsed his butt really well so Ginger wouldn't tease him about his sweet smelling butt.
Then I wrapped him up in a towel and dried him off really well before putting him back in his cage.
He was a really good boy through this whole thing. He seemed to understand that I was trying to help him.
All in all, I think that went pretty well.
I can see that Cetaphil or coconut oil would probably remove it better than what I did. I have coconut oil. Has anyone else tried that? Someone mentioned it in the thread that I mentioned above.
Oh, man, I was so panicked. I'm glad that's over.
