All the information BluuWolf gave you is perfect. Follow it. The only thing left out was don't worry about your Ball feeding this week. He had 2 mice last week and may not be that hungry at this time. Wait till next feeding day. At that age 1 appropriate sized mouse a week is plenty. I actually went to a feeding every 2 weeks on my snakes due to the hit / miss eating. The yearly feeding average still equals out for me. The only snakes that get 2 a week are my Gophers but they are pigs and gophers will tend to over eat anyways. (The lady I got them from was feeding each 6/week. way too much). My larger 2 Balls (over 3 foot) sometimes take 2 also but one has refused to eat for 6-8 weeks before. Yesterday was the first time everyone ate in a looonnnggg time. As far as bedding goes, I use the coconut bedding myself. Aspen is used only for my Desert King just so he can burrow in it. He is a wild born I caught 2 months ago so the aspen suits him better. That type doesn't need the humidity the Balls need. Hope this helps a little better. Oh, yes, throw the pad away. it is no good once removed and if ever one is used, put it on the side of the tank and not the bottom on the same side as the lamp (warm side). You don't want to cook your snake which on the bottom it can do.
