I keep my Dumeril Boa in an AP 4ft cage. Have had him a couple years now. Recently I noticed a sore on his head. I sent a pic to a friend and he thought it looked like a rub. Told me to put triple antibiotic ointment on it and it would go away after a few sheds.

My concern is that there is nothing in the cage to rub on except possibly the Pro Products RHP but that seems unlikely.

Just wondered how common this sort of thing is. I've been keeping snakes for almost 10 years now and never had this happen.

Thanks.
