Sugar Gliders enjoy  variety the same as you and I.  It may take a little experimenting on your part to discover what your pet likes.  They enjoy a variety of fruits and vegetables; however, they tend to prefer sweet varieties.  Make sure you thoroughly rinse all fruits and vegetables to remove pesticide residues. Large chunks or small pieces depend on your Glider: Experiment.  Frozen vegetables are also ok to use: NEVER CANNED.  Be aware that apple seeds are toxic.  In addition, they enjoy live insects such as crickets and meal worms available from a pet store.  Boiled chicken breast or turkey breast is a good source of protein as is scrambled or hard boiled eggs.  Tofu also falls into this category.  Yogurt with fruit from the dairy case at your grocery store and baby food fruit can also be used as a licky treat.   Salt is very detrimental to Sugar Gliders.  It can dehydrate them very quickly and cause potential life threatening situations.  Raw unsalted nuts are a good source of protein, but they have a very high fat content and should be strictly rationed.  An obese Sugar Glider is very unhealthy and will suffer from many problems.  The normal weight is between 3 to 5.5 ounces or 86 to 156 grams.
