So I have noticed that all of my leopard geckos seem to only use their cool side hides as the spot to go to the bathroom. Each tank has 3 hides and I see them use the hot and humid hides but they never use the cool side one. I always have to clean it out cus thats where they poop. Leos are in seperate tanks but they all seem to do it. Should I add a 4th hide to the cool side? I am not sure they would use it.
