Hi all! I’m new here but I’ve had my girl for around 2 years. She’s a jungle python. I have noticed this a bit lately; I just checked her temp and she is at 18 degrees, but her heat mat is on and she isn’t going to it. I don’t understand as it’s quite cold at the moment and I’ve read snakes shouldn’t go under 21 but I obviously can’t force her onto it. I’m just a bit worried! I’d appreciate any and all advice thanks in advance.
