Mine have been getting lots of tomatoes of which they leave no trace of. I had/still have late tomatoes in the garden and I get culled ones by the box from a produce store. I also buy dried "bugs" by the 5# bag (crickets, mealworms, river shrimp and sunworms) but most often they get dry feed for treats. I ferment their purina feed so they think the dry pellets are treats and go crazy for it.
