I finally went and got some live crickets for the critters. They'll eat the canned crickets when they have to but they prefer to hunt for their food.
<---This is Junior, the Leopard Gecko. I snapped this pic right before he gobbled up that little cricket underneath him.
<----This is Gecko, the Bearded Dragon. When he hears me coming up the stairs, he perches on this rock, waiting for me to drop the crickets in.
<----He's ready to pounce!
