So Confused

[Soup]

My ball python used to switch hides but now she just stayed in her cold hide no matter what temperature it was. I cleaned her cage and now she only wants to be in her warm hide no matter what temperature it is. I havnt changed anything and she has eaten, so i dont know. Any suggestions?

Normal behavior.... balls will always be throwing curve balls at you, just when you think you have them figured out they do something weird and bug you out with worry
