I fed my ball python on saturday, july 28th, and he ate 3 fuzzies. He is around 16-20" so i thot this woold be enuff,but when i went to put my hand in to check the heat mat he bit. I was just wondering if maybe i shoold feed him another one 2day and start feeding him 4 when he feeds(until i run out, then ill switch to hoppers) ? Also, if ne1 has a macs creatures and critters small pet refuge, what size shoold i get for mine?
