I just had to clean two piles today. My male lesser decided he would try to paint-by-numbers inside his tub. He had poop EVERYWHERE. In the water bowl, on top of the hide, inside the hide, smeared on the side of the hide, etc. And I looked him over to see if he needed to be cleaned up...he was squeaky clean.
The other one was less impressive. she always poops in the cold side hide about every 2 weeks and today was no different xD
I also have another one who holds it in until she can't anymore.
These are all 400-600g snakes. I can't imagine what my 2000g will do...
