A healthy sugar glider diet is built on three things: a quality staple food with animal protein first, a small amount of fresh produce and appropriate insects, plus calcium and vitamin support your exotics vet approves. Despite the name, sugar gliders shouldn't live on fruit and sweets. Many of the health problems exotics vets see in pet gliders, including weak bones and dental disease, are linked to poor diets.
At SunCoast Sugar Gliders, we've focused on premium nutrition for exotic pets since 1999. Here's a clear, practical look at what sugar gliders eat and how to build a diet that supports a long, healthy life.
What Do Sugar Gliders Eat in the Wild?
Wild sugar gliders are omnivores. They feed on plant exudates such as sap and gum, nectar and pollen, and a wide range of insects and other small invertebrates. What they eat shifts with the seasons. In a home, you can't recreate that menu exactly, which is why a well-formulated staple food matters so much.
The Foundation: A Quality Staple Food
A staple food gives your gliders consistent nutrition every day. When you compare foods, look for:
- Animal protein as the first ingredient, such as chicken
- No soy or cheap fillers that add bulk without much nutrition
- Human-grade ingredients from a maker that tells you where the food is made
- A texture your gliders will actually eat
SunCoast makes two sugar glider staples:
- Wholesome Balance chicken & brown rice: our protein-forward staple. It's Soy & Filler Free, human-grade and Made in USA.
- Happy Glider Fruity: a fruit-flavored staple that tempts picky eaters while keeping nutrition front and center.
See both in our sugar glider food collection.
Fresh Fruits and Vegetables
Fresh produce adds variety and moisture. A few guidelines:
- Keep fruit small. Fruit is a treat-like favorite, but too much can crowd out protein and calcium.
- Favor vegetables. Many gliders enjoy leafy greens and other veggies that provide nutrients without as much sugar.
- Wash everything and cut it into small, glider-sized pieces.
- Remove seeds and pits. Some, such as apple seeds and stone-fruit pits, can be harmful.
- Introduce new foods slowly, one at a time, so you can spot any that don't agree with your glider.
Never offer canned fruit in syrup, dried fruit with added sugar or fruit that has been sprayed and not washed.
Insects: An Important Protein Source
Insects are a natural part of a glider's diet and a favorite treat. Commercially raised mealworms, crickets and other feeder insects are good options. They're easy to buy or raise yourself; see our guide on how to raise mealworms at home.
A few rules:
- Never feed wild-caught insects. They may carry pesticides or parasites.
- Use insects in moderation. Some, like mealworms, are high in fat.
- Gut-load feeder insects with nutritious food before serving to make them more valuable.
Calcium, Phosphorus and Supplements
Calcium is one of the most important nutrients for gliders. A diet that is too low in calcium, or too high in phosphorus compared with calcium, has been associated with metabolic bone disease and hind leg paralysis in sugar gliders. Our article on the calcium to phosphorus ratio for sugar gliders explains why balance matters.
Supplements can help fill gaps, but more isn't always better. Ask your exotics vet whether your gliders need a vitamin or calcium supplement, and follow product directions. Our Blueberry Fortifier Supplement is one option to discuss with your vet.
Water
Fresh, clean water should always be available. Use a water bottle, a bowl or both, and clean them often. Check bottles daily to make sure they're working.
Foods Sugar Gliders Should Never Eat
Avoid these:
- Chocolate, candy and sugary human snacks
- Caffeine and alcohol
- Raw meat and raw eggs
- Fruit pits, seeds and canned fruit in syrup
- Wild-caught insects
- Foods treated with pesticides
For a full list, read our guide on what not to feed sugar gliders.
Tips for Picky Eaters
Gliders can be stubborn about new foods. Try these:
- Offer food in the evening when your gliders wake up
- Mix a little of a familiar food with a new one and shift gradually
- Offer foods at room temperature
- Remove uneaten fresh food in the morning so it doesn't spoil
If a glider stops eating or loses weight, call your exotics vet. Appetite changes can be an early sign of illness.
Frequently Asked Questions
Can sugar gliders eat only fruit?
No. A fruit-heavy diet lacks enough protein and calcium. Use a quality staple food as the foundation and keep fruit a small part of the menu.
Do sugar gliders need supplements?
Some do, depending on their diet. Ask your exotics vet before adding any supplement, since too much of some vitamins can be harmful.
What is the best staple food for sugar gliders?
Look for animal protein first, no soy or fillers and human-grade ingredients. SunCoast's Wholesome Balance and Happy Glider Fruity were developed with those goals in mind.
Conclusion: Feed for the Long Run
The best sugar glider diet is simple and consistent: a premium staple, a little fresh produce, appropriate insects, fresh water and vet-guided supplements. Skip the sweets and your gliders will thank you with energy, a healthy coat and many years together.
