i asked my SO (i think he could be the next reptile man) and this is what he said.
fruits like strawberries, blueberries, apples, prickly pears/cactus fruit, melon rinds, grapes, mango,
grasses like hay and alfalfa, lettuces, squash, carrots, worms, dandilions,
he said they are basically vegetable garbage disposals lol.
if your still not really sure or want a direct list google it.
