I like the idea of an upgrade but I'm always quick to say that and feel bad for my big girls in their 41 quarts. I have read in several books one of which was written by some one very reputable in the business for over 25 years and another by some one who's been in zoology for a life time but also my own hours and hours of online research going through old posts, blogs, and general information. I am not saying it's abnormal for a ball python to soak for reasons other then what I stated but if it is a prolonged and frequent thing then I would assume something is off. I would not recommend not inspecting further if I found my ball python soaking for more then a couple days as it is for a fact not a normal thing for them to soak that frequently when all else is correct.
