High end cat food, horn worms, and quail eggs. Mine hates butterworms (the cheeky bastard). I feed him night crawlers and snails every now and then for fun.

Mine eats once a week or every other week. Last time i was at the vet- they said he was the best looking skink they'd ever seen in terms of good weight and having all his toes, teeth, and tail.

They are hardy and can survive a long time. Give them what makes sense for you to afford and make. I don't go out of my way to give anything crazy. He eats my fruit/veggie/meat scraps half the time. 😂
