I haven't had my Skull for very long but yeah, he's got an appetite. The only time he ever refused prey was due to a N00B mistake we made in letting the prey get too cold before we offered it. I warmed the mouse back up, my husband offered it again and ZAP! We feed F/T and it generally takes him less than a minute to sight and zap it. We've been feeding him two mouse fuzzies every 4 days. I know a fuzzy sounds small but they were a little larger than his girth. However, his girth has been getting bigger lately so we're going to switch over to larger prey after he sheds.
