My ball python is approximately two and a half months old and is housed in a 20 gallon long Zilla Critter Cage. I have two identical hides. One on the warm side and the other on the cool side. The hides I am using are from Reptile Basics. For whatever reason she has been moving the hides the last couple of days. When I say she is moving the hides I mean she is moving them approximately 5 to 6 inches........completely away from her warm spot. Obviously, the easy solution is to have heavier hides but the ones I have seen at local pet stores are too big. Which hides do you all recommend?
