I have been feeding Pretty Pets Sugar Glider food to my gliders for years and they love it! I don't use it as a primary food source because I feed them fruits and vegetables every day, but I always keep it at their disposal. It keeps their coat and bone structure nice. If you are changing your gliders diet you can mix a small amount of Pretty Pets with "Gerber's Turkey and Rice" or "Turkey and Mixed Vegetables" with a small amount of honey. Any change in the gliders diet needs to be small and balanced.
I recommend this not as the only food, but also a vitamin supplement that should be kept available at all times.
