Sugar gliders are lovable, social, and active creatures, but like all pets, they can be susceptible to certain toxic substances. As a responsible sugar glider owner, it’s essential to know what foods, chemicals, and environmental factors could harm or even threaten the health of your pet. In this guide, we’ll cover what is toxic for sugar gliders and how to keep your furry friend safe from harm.
1. Toxic Foods for Sugar Gliders
Sugar gliders are omnivores and have specific dietary needs. However, some common foods are toxic to them and should never be included in their diet. Here are some key foods to avoid:
Citrus Fruits:
While sugar gliders enjoy a variety of fruits, citrus fruits like oranges, lemons, and grapefruits should be avoided. The acidity in these fruits can upset their digestive system and cause discomfort or diarrhea.
Chocolate and Caffeine:
Both chocolate and caffeine are toxic to sugar gliders. Chocolate contains theobromine, which is harmful to most animals, while caffeine can lead to heart palpitations, seizures, and even death if ingested.
Avocado:
Avocados contain a toxin called persin, which is harmful to sugar gliders. Even small amounts of avocado can lead to serious health issues, including respiratory distress, heart damage, or even death.
Onions and Garlic:
Both onions and garlic, whether raw or cooked, are toxic to sugar gliders. These foods can cause digestive upset and blood cell damage, leading to lethargy, weakness, and anemia in severe cases.
Alcohol:
Just like humans, alcohol can be incredibly dangerous for sugar gliders. Even small amounts can cause poisoning, leading to vomiting, seizures, and potentially fatal outcomes.
Nuts and Seeds (in large quantities):
While small amounts of unsalted, unseasoned nuts and seeds are safe, too many can lead to obesity and other health problems due to their high-fat content. Some nuts, such as peanuts, may contain harmful molds called aflatoxins.

2. Toxic Chemicals and Household Substances
Apart from food, there are several chemicals and household substances that can be toxic to sugar gliders. These include:
Cleaning Products:
Many household cleaning products, such as bleaches, ammonia, and harsh detergents, can release fumes that are harmful to sugar gliders. Always use pet-safe cleaning products and avoid exposing your sugar glider to harsh chemicals.
Pesticides:
Pesticides and insecticides used in gardens or around the home can be toxic to sugar gliders. Make sure that any products you use to treat plants or the house are non-toxic and safe for small animals.
Essential Oils:
Many essential oils are toxic to sugar gliders. They can cause respiratory distress, irritation, and other health problems. Never use essential oils around sugar gliders, and avoid air fresheners or diffusers that contain these oils.
Non-Stick Cookware:
Non-stick cookware (like Teflon) can release toxic fumes when heated to high temperatures. These fumes can be deadly to sugar gliders and other small animals. Always use non-stick cookware with caution and ensure it doesn’t reach high heat while your sugar glider is nearby.
3. Unsafe Environment and Stress Factors
While not always immediately toxic, certain environmental factors can cause harm to your sugar glider over time:
Extreme Temperatures:
Sugar gliders are sensitive to temperature changes. Too much heat or cold can lead to stress, illness, or even death. Keep your sugar glider in a stable, comfortable temperature range of 65–85°F (18–29°C).
Loud Noises and Stress:
Sugar gliders are sensitive to stress and loud noises. Constant exposure to stressors, such as loud music or excessive handling, can cause anxiety, health issues, or behavioral problems.
Unsafe Cages:
An improperly secured or poorly designed cage can be dangerous for sugar gliders. They are escape artists, so ensure the cage is strong, with no gaps large enough for them to squeeze through. A poorly maintained cage can also lead to injury or illness.

4. Toxic Plants for Sugar Gliders
Certain houseplants and garden plants are toxic to sugar gliders. Be cautious when adding greenery to their environment. Some toxic plants include:
Pothos (Devil’s Ivy):
This common houseplant is toxic to many pets, including sugar gliders. It can cause digestive upset and irritation if ingested.
Dieffenbachia (Dumb Cane):
Another popular houseplant, Dieffenbachia contains oxalates that can cause burning and swelling of the mouth and throat if eaten by sugar gliders.
Sago Palm:
All parts of the sago palm are toxic to sugar gliders and can cause severe liver damage or death if consumed.
5. Signs of Toxicity or Illness in Sugar Gliders
It’s essential to be vigilant about any signs of illness or poisoning in your sugar glider. Common symptoms of toxicity or distress include:
- Lethargy or unusual fatigue
- Loss of appetite
- Vomiting or diarrhea
- Difficulty breathing or wheezing
- Seizures or twitching
- Sudden aggression or fear
- Excessive grooming or scratching
If you suspect your sugar glider has been exposed to something toxic, contact a veterinarian immediately, especially one familiar with exotic pets.
Keeping Your Sugar Glider Safe
Sugar gliders are sensitive and delicate animals, and keeping them safe involves knowing what to avoid. By being mindful of toxic foods, chemicals, and unsafe environments, you can ensure your sugar glider stays healthy and happy.
Always research before introducing new foods, plants, or substances into your sugar glider’s habitat. If in doubt, consult a veterinarian who specializes in exotic pets to get the best care for your furry companion.
