So I just got my first Ball Python and she is beautiful. At first I was a little timid and scared that I might mess up but once I had it all set up and she ate I calmed down. My main question is when do I know that she needs to move up in size for the feeder mice. right now shes on fuzzies but i would say that they aren't any where near as thick as she is, they're probably 3/4 the size of her thickness. also I dont have a scale. I plan to by the digital temp/hydrometer soon alone with the temp regulator that I saw at the store, are those any good for the lazy guy who really doesnt want to constantly turn lights and heat pads on and off?
