I've never heard of feeding Gliders snails, silk worms or caterpillars. The pellets from
www.thepetglider.com are THE ONLY pellets I would EVER recommend if you absolutely must feed pelleted food. I would never suggest feeding a pelleted diet, however. Stick to the proven diets, such as The Priscilla Price Diet, BML or HPW. Oh, and don't vary them, it mixes up the ratios!
I love Lisa (the owner of that site), she is very kind and has helped me out a lot over the years. She seems very knowledgeable regarding her Gliders and really does care about them. Although a lot of people would disagree and say that they don't like her business, I personally have found her to be very helpful!!! I have my own preferred breeder though, Priscilla Price is one of the only people I'd ever purchase a Glider from. When hers arrive, they are so sweet. My biggest baby, my mama's boy, came from her, he's the one pictured in my display picture, my Scooter! =P
