I'll have to keep watching him. It would be funny if he poops in same place everyday.My Aldabran tortoises wake up in the a.m. and just sit there in their house or in a corner of the yard - wherever they happened to go to sleep at night. After about a half hour they will raise up and look like they're in the zone, then after a bit poop and pee comes out. Then they go outside and sit in the sun before wandering around grazing. They DO poop throughout the day, but never in a certain spot. Just wherever the spirit moves them.
Got the box in place stays between 85-90f no matter temps outside.
