Mine likes to poop right in the middle of his basking rock. It leaves me annoyed because it is never a time when I am home, so I have hard poop I have to scrape off the stone. It is real rock which is glued to two other rocks which makes for a heavy item to lift out of his cage. If it is not on the basking rock it will be behind it or on the log that rests against his basking rock. He just likes to poop hot I guess.
On a side note, if you ever come into my pet store (I work for petco) I only recomend carpet. I will tell the buyer about the dangers of sand, and only sell it to them if they say they want it. I know not all pet store employees are worth their weight, but some of us are. When I am shoping, I always ask if the person owns what I am shoping for and if they do not I ask them where their knowledge comes from. This way I know how much weight to put into their advice.
