I agree HPW Complete and Glide-R-Gravy are the same product. So is SmartHPW. HOWEVER, please consider how each site suggests they be served if you choose to use this diet.
Peggy Brewer's HPW Diet center is the ONLY one of the three sites (the other two being Pocket Pets and ASGV or Vetspride.com) to instruct it be served with fruits and veggies only. If you are feeding HPW Complete this way be aware that it's crude protein content is 14% and crude fat content is 2%.
The other two sites SPECIFICALLY say it is used to enhance the taste of their staple diet. They both instruct that the product be served over their kibble. Pocket Pet's kibble is Glide-R-Chow and ASGV (Vetspride) suggests the same kibble only it's called NutriMax. The kibble is the same product and it contains not less than 20% crude protein and not less than 10% crude fat. Of course they say you can feed it with fruits and veggies (we know they suggest apple wedges). They make it a point to say that the nectar product is an excellent ADDITION to their pellets served on TOP. It is not intended to replace their pellets.
I think this is a very important fact to consider.
Btw, WHY is it so much better to buy directly from HPW Diet Center and not the other two organizations? The products are the same. You are supporting a business. Peggy Brewer has said on numerous occasions she has worked with the owner of Pocket Pets regarding this diet. I am confused on this point of trying to steer people to buy from her instead of the other two sites. Personally, I would say that I would most likely choose to purchase from Vetspride.com at this point. ASGV is an organization for exotic vets to work together and discuss sugar gliders. It isn't controlled by Pocket Pets any more than HPW Diet Center. IMO
