Ok, we feed our guy a mix of two kibbles, plus some enrichment/treat things:

NUTRO WHOLESOME ESSENTIALS Adult Weight Management Natural Dry Cat Food for Weight Control Farm-Raised Chicken & Brown Rice Recipe, 6.5 lb. Bag

Suncoast Sugar Gliders Spike's Delite Hedgehog Premium Diet Food 1.5 lb

Treats:

Mealworms, Darkling beetles, Dubia cockroaches, Pinkies (baby mice, we get frozen and defrost as needed)

Our guy has never been into any other fruits/veggies/meat/fish, except we did get him to eat a little cooked ground beef.

Hope this helps!
