PP Glider Chow I believe is PetPro's Happy Glider in fruity flavor. This is a popular brand used by many who do serve pellet food as a side (never a staple.)
It is best to use a nectar formula, two popular ones are BML and Critter Love (CL.) Critter Love Complete (CLC) is also marketed by PP under the name "Glider Gravy" and is also a top-notch, popular choice by many sugar glider owners. You will most likely find a better deal for these foods from original websites.
Critter Love
for the nectar, and instructions for preparation, storing (if necessary), and serving. Also pay mind to the salad mixes, as they're considered part of this diet plan for calculated ratios and nutritional needs. Peggy (creator of the original HPW diet and CL, trademarked diet) also offers alternative recipes for the nectar, CL Plus would be the most similar to the Original HPW diet, which is also now know for Critter Love Original (TM) and that recipe is also available on her "diet page".
PetPro-Happy Glider Pellets
There are several varieties, PP sells the "fruity" flavor, and that's the one my trio prefers. They offer a trial package I believe so you can see which is preferred before buying large qualities.
Hope this helps.
