Mine is a ball python. They seem to prefer basking under the heat lamp after eating. Also they haven’t ever pooped in their water dish that I can remember, but I have had them horf up a partially digested rat in there before. That incident was made even more pleasant by the fact that I had their heat lamp positioned over the water dish at the time (to try and keep humidity up) and it happened while I was sleeping so I didn’t catch it for several hours. So I awoke to my entire house being filled with the miasma of a partially digested rat which had been stewing under a heat lamp for several hours. The smell was indescribable and beyond the imagination of any sane individual.
