My bp ate two f/t hoppers yesterday (he needed the extra food but isn't big enough to take a mouse yet) and one of the hoppers had a belly burst when he struck at it, so it made a bit of a mess. I cleaned it out today and I noticed when I took him out to replace the paper towels that under his chin there's a weird fold of skin, like if it was pinched between someone's fingers and never went back... What could this be? I thought maybe there was something wrong with the humidity, but it's been constantly between 50 and 60% so... :S
