So i just got my first ball python, or snake, ever and i have her in a plastic tub, around 15 gallons with the dimensions being around 36x15x8. I have a thermometer, and it says the temp of the cage is around 80 degrees. i don't know if I'm reading the thermometer correct, because it gives me a max and min temperature, and i can't figure out which is the right temperature. But either way, what are some options for heating the cage up more? i am not looking for an expensive solution, cheaper the better, as long as it works. Also i just got her on the 9th, it is currently the 12th, and I've tried to feed her twice but she won't eat. (the breeder i got her from told me she would probably eat by today. The snake just seems uncomfortable and doesn't want to be touched. I am worried she isn't in a comfortable environment. Also her humidity in the cage is around 57% or so it says, again i don't know whether to go by the max or min temperature/humidity. The min humidity is like 37%. If someone could help me figure what I'm doing wrong or what i need to change please let me know so i can get her comfortable as fast as possible! also if there is anything you need to know that i haven't said let me know. Thanks!
