Ok, so now we are a bit off topic...
@ jerison, the diet you are feeding is going to need tweaking. the glider gravy is HPW complete sold by Pocket pets and is actually the best thing you are feeding him. Feed him the recommended amount and wean him off the pellets. ( I think the serving should be 1 tablespoon).
Offer him 1 table spoon of fresh or frozen fruit and 1 tablespoon of fresh or frozen veggies(No onions, leeks or garlic...they are toxic)he needs more variety than just aplles and grapes and don't sprinkle anything on his food.
If he is on the HPW complete you should not need them.
If you are going to feed him a staple mixture where you just add water like glider gravy I would order it from critterlove.com...she has the best prices and was the creator of that diet.
Look at the diet tab and go thru the ingredients of each to see if any are doable for you. www.gliderkids.com has a great page of diet info to compare recipes too.
please Pm me if you want or need more info ok ?
