I don’t usually post here anymore but you need some help.
At wall mart you can buy temp probes for about 5 bucks. Temps are Extremely important for ball pythons. They are from the desert so the high humidity is not really needed. It’s ok to spray them right before they go into shed but that’s all.
I use aspen bedding from tractor supply its the cheapest i can find. If the heating pad you are using is the kind that sticks to the bottom of the glass they can get way to hot. Upwards of 115 degrees. You need to put some kind of temp control on it. I use these to heat all my racks and have never had a problem with them. http://www.bigappleherp.com/BAH-1000-Thermostat
Make sure you have at least 2 hides in the cage. One on the hot side and one on the cool side so the snake can thermo regulate. On the hot side try and keep the temps between 88 and 90 degrees. They need it to help them digest their food.
