Wait another two weeks and then offer a feeder a size lower than what he was eating. If that stays down you can offer a small meal again in two weeks, then in a week, and then resume your normal schedule.

In the meantime go to TheBeanFarm.com and order some NutriBAC - it's a reptile probiotic powder that you can dust onto his feeders. It will help re-establish his good gut flora.

I usually wait 72 hours after feeding before handling.
