When people are not asking me about fun things to do and what equipment, they are probably asking something about my 2 inch babies. The most asked thing is what to feed them. So I repeatedly tell about food for sugar gliders/sugar bears. Do you know how far these amazing animals can jump? They launch, then can float on the air for well over 10 feet(more then 50 times their body length) so they really have only one correct name. The other nickname has only recently popped up and if you see one of these sweet things act like a big ferocious grizzly, know it is a defense mechanism and that individual has been or is currently being mishandled. In any case, if you are interested in owning one, one of the things you need to know what to feed them. On this important topic opinions vary drasticly.
There are several schools of thought. And lots of "experts" will tell you lots of different things and even try discredit other "experts" because they think differently. I guess its kind of like the diet of people. Some places we eat mostly plants, others lots of meat, and some even eat insects. Pretty much all do OK on the diet of their region. All pets are somewhat the same. Back to what the experts say about these little "pocket pets" and what they eat. In nature they thrive. Insects and sometimes even really small animals are their pray. They also eat some nuts and such. A surprising thing though is they love melons, sap and honey. For almost 20 years, mine have had a core diet of dry food. I supplement that at times with treats of yogurt, live meal worms, boiled eggs and cooked chicken. Often if I catch crickets or grasshoppers they go in the cage too. And melons and grapes and a lot of apples. If I am out for the day and have one in a pouch, there is always a slice of apple or some kind of melon or fruit. The baby gets liquid and nutrition both from it and no extra water needed.
When buying online I like 4 star ratings but also watch the nutrition value. The main part of our diet is the first two selections on this list. When given the choice, some of my companions prefer one, others want the other. Go figure. The second choice shows the label instead of the food. The food itself is small beads and lots of colors. Just so you know I watch the ratings, but take it from someone who has raised her own colonies of these pets. Both of these dry foods are good as a base diet. It is possible you will have an animal that has a reaction to something just like people can be allergic to things like peanuts or gluten. Live food is another angle. If you catch grasshoppers for example they may have been sprayed with pesticide. Don't do that. Unless you live in an area and know you are safe then its OK. I have caught cicadas (katydid) as large as the gliders and they grab them and eat the head first. It is awesome to watch. Anyway, live food is good and can perk up a mopey suggie. If you can stand to touch the worms or insects that is. I put crickets with the animal into a hamster ball. Worms I hand feed or just put in with their dry food as a surprise. I have never purchased worms online but may next time because it sure is more convenient. Then the monkey biscuits are another piece of variety. I get the kind I listed and make sure I seal them up. I put 1 or 2 in a cage and just leave them. Then few days or weeks later I give them more. I use the calcium shown here as well, but mostly with my joeys. Once they reach adult I occasionally sprinkle it on their food too, but as the young grow I always make it available in good supply for their developing bones. The 3 dry foods will last months if you just reseal the bag. Calcium also lasts for months. Meal worms, if not kept in the fridge will morph into beetles so do keep them chilled. They will not last to long in the fridge, but I have had them for over a month from getting home until "spoiled." The worms will barely be moving when you take them out of the fridge, but they perk up when they warm up. Any that are black have passed and won't be eaten so don't even offer them.
Back to the experts now. You should listen to each point of view as they mostly are all right but each also has weaknesses. If you feed a lot of fresh fruit and veggies, or a lot of live food the cage will need to be cleaned more often to avoid smell. I will go a week or even two between cleaning and mostly dry food with some yogurt chips and meal worms on occasion. When nearing time to change the litter, I increase the things that make the smell and over the years found my "kids" do great on this diet.
