It looks like a great setup.
You can sit on the couch and watch they take a dip in the pool and poop in it
My snakes seem to relish me changing the water. They come out to watch the whole process. They even jump in while I'm pouring the new water. Then within a few minutes they poop in it.
Then it's back to their hide. Probably laughing all the way. Once back in the hide the others give the perpetrator a high-five(metaphorically speaking)
