There are quite a few well known diets in the USA like the BML, HPW and the Priscilla Price diet. Sugar gliders don't usually like pellet-type food (ours didn't when we gave them a bit to try) and it isn't considered that nutritious. We gave our sugar gliders boiled chicken (with a bit of coconut oil) and scrambled eggs with small fresh chopped pieces of fruit and veg at first and then moved onto a blended diet with vitamins from Exotic Nutrition we found online, the SGS2 diet. Hope that helped a bit!
