I don't think you really need to invest in a carrying case. I just buy like a $5 plastic tub for food or sew my own bags, probably much cheaper and worthwhile than spending $30 on a case and the snakes really don't care one way or another.
Just what ever you do, don't buy anything with a metal door or slots in it because BPs will try to get out through them and they can get injured.
Oh okay.
Do you think he will be okay in a bag or plastic bin for the time it takes me to clean his cage.
The case that I am getting him is pretty cheap so I really don't mind.
