My ball pythons cage has a water bowl and 2 caves, one on the cold and warm side, But there was a bare corner that had nothing in it so i decided to just put a hill of aspen there because it looked better. This morning i woke up and the ball python wasn't anywhere! so i thought about the hill and i stuck my hand in the pile of aspen, and surely it was there! He used the aspen as a cover and loves it and doesn't use the caves anymore! The temperatures are also perfect and same with humidity. Is this a safe thing for the snake? Or.. can the aspen affect its health? Why is it doing this?
