Well I fed him a 30+ gram mouse and he is 81 grams, and I know it was too big but he ate it easily! I am so proud of him! Now he is resting and digesting on the UTH (which is regulated by a thermostat of course ) but I had a post about feeding inside or outside the enclosure and I decided to feed inside. I moved him out of his hide, held the mouse by the tail in front of him and BAM! He struck it like a champ and coiled around it, killing it in a very timely manner. I am so proud of Spidy!
