Well, just like anything you have to do the research.
There will always be someone who will feed this or that or won't for whatever reasons.
It is a personal choice, I think we are all here to learn what is best for our gliders. Some of the recognized staple diets ingredients are hard to get especially for those out of the U.S. the shipping rates are high.
There is a diet that is all ingredients you can get from your grocer and pet store.
But people feed their gliders cheetos and cat food...Not that they will live long healty lives but that is the unfortunate mistake they will make and the glider will be the one to suffer for it.
(pushpabhawan: " and stopped giving HPW which I tried to give once. Tinker did not like it anyway...")
And if you feed a glider something once and they "don't like it", is not a true test of if they will eat it. I offer mine things that they have passed on in previous feedings and sometimes they do eventually decide to eat it.
