Query: if it doesn't move, it won't go in their mouths

I have leopard geckos, and if your pet is anything like my two, the rule is this: if it doesn't move, they won't eat it. If, for whatever reason, your gecko won't eat, force feeding them this stuff is nearly impossible, not to mention stressful for the little guys, so if they get sick (which mine did once--intestinal parasites from an irreputable dealer), go to the vet. What often happens is (s)he gives you a syringe (not the really pointy kind, but the plastic-tipped, somewhat wide kind), and you use what they give you (usually some protein type mix) or meat flavored baby food, if the vet says it's ok. If you don't have to force feed them, then go with live food, just as nature intended.
