Many disorders and diseases that occur in sugar gliders are related to dietary imbalances, including malnutrition, obesity, and vitamin and mineral imbalances. Others are related to infection with bacteria, fungi, or parasites.
Aflatoxicosis is a liver disease caused by toxins produced by certain fungi in or on foods and feeds. Corn, peanuts, and cottonseed are the most likely to be contaminated with aflatoxins. Sugar gliders can get aflatoxicosis by eating contaminated peanuts or by eating crickets that have been fed contaminated corn. Therefore, it is important not to feed your sugar gliders peanuts and to know what kind of feed your insect supplier feeds its insects. Signs of aflatoxicosis are loss of appetite, anemia, jaundice, lack of energy, and diarrhea. Sudden death may occur. If diagnosed in time, aflatoxicosis is reversible. Take your sugar glider to a veterinarian immediately, and change its feed.
Small, hard, dry droppings, or none at all, may be a sign of constipation. Possible causes of constipation are not enough liquids or fiber in the diet, poor overall diet, stress, lack of exercise, or digestive system problems. Some medications can also cause this problem. A medical examination by a veterinarian to determine the cause should be performed as soon as constipation is noticed.
Several microscopic parasites, including Cryptosporidium, Giardia, and Trichomonas, can cause diarrhea and occasional vomiting, along with abdominal cramps, weight loss, and dehydration, in sugar gliders. Your veterinarian can perform tests to determine the cause of these signs and prescribe the appropriate medication. Because several of these parasites can also infect humans, it is important to use care when handling sick sugar gliders and to wash your hands thoroughly after cleaning the cage and before touching any food or any item that will be near your mouth. Until a follow-up test shows that the parasite has been eliminated, the sugar glider should be quarantined from other pets. The cage should also be thoroughly cleaned to reduce the possibility of reinfection. Bacterial infection, malnutrition, stress, and other disorders can also cause diarrhea in sugar gliders.
Sugar gliders may be aggressive and can cause trauma to each other, particularly during mating and the introduction of new adults. These injuries often occur around the face. Eye injuries may include scratches of the cornea. Corneal scratches may result in slow-healing ulcers of the cornea and conjunctivitis (inflammation of the tissue around the eye). Cataracts (white spots in the lens of the eye) also occur in sugar gliders. As in humans, cataracts can lead to blindness.
Sugar gliders may become infected with this disease and pass it to humans if they come into contact with water or food that has been contaminated with Leptospira bacteria. Signs include fever and kidney and liver problems. A veterinarian can test for the presence of these bacteria. Strict attention to thorough cage cleaning, food dish and water supply sanitation, and careful hand washing following contact with your pet or its environment are important to prevent both reinfection and transmission to you or other humans.
Lumpy jaw is a condition in which the bacteria Actinomyces israelii infect the face and neck, creating a slowly enlarging, hard lump. The bacteria can also infect the lungs, intestinal tract, and other parts of the body. Discharge from the eyes and weight loss are other signs of infection. Sugar gliders can become infected with the bacteria after undergoing surgery, trauma, or another infection. A common cause in sugar gliders is an abscess in the mouth. Lumpy jaw is deadly if left untreated. Therefore, you should contact your veterinarian immediately if a hard lump appears on the face or neck of your pet or if you notice eye discharge or sudden weight loss. Treatment to get rid of the infection requires a prescribed medication. Because several disease-causing organisms may be involved, your veterinarian will perform tests to determine the most effective medication.
Hypocalcemia is an abnormally low level of calcium in the blood and is due mainly to an imbalance of dietary calcium, phosphorus, and vitamin D. Not getting enough dietary protein causes hypoproteinemia and anemia (too few red blood cells). All of these conditions may be caused by long-term malnutrition and can lead to liver and kidney problems. Malnourished sugar gliders are weak, slow to respond, and usually thin and dehydrated. Anemic and hypoproteinemic sugar gliders may also have bruising, abnormal swelling, and pale mucous membranes. Weakened animals may develop additional infections. Treatment requires correcting the underlying dietary problems and providing general supportive care. Follow your veterinarian’s advice regarding diet, supplements, water supplies, and environmental conditions.
Metabolic bone disease, also known as nutritional osteodystrophy, is a softening of the bones due to an imbalance of the minerals calcium and phosphorus in the diet. The first sign is often weakening of the rear legs, progressing to paralysis. This can seem to happen very quickly. Pneumonia, heart problems, seizures, and broken bones can also occur as a result of this condition. X‑ray images reveal a loss of bone from the spinal column, pelvis, and leg bones. This disease, if treated quickly, can be reversible with proper diet and care. Treatment involves cage rest, giving calcium and vitamin D3 supplements (which your veterinarian may give by injection), and correction of the diet.
To help prevent vitamin and mineral imbalances, insects in the diet can be gut-loaded with calcium or sprinkled with a calcium powder before being fed to sugar gliders. Gut loading is a common technique that involves giving insects a nutritious mixture of cereals and vegetables immediately before being fed to the sugar glider—thus loading their gut with nutrients. Another common practice is the use of powdered vitamin/mineral supplements. Crickets brought home from a pet store and never fed have little nutritional value. Placing them in a bag with vitamin and mineral powders and shaking the bag will coat the insects with the powder. Although some of the powder will fall off, the newer microfine powders adhere remarkably well.
Polioencephalomalacia is a neurologic disease that causes deterioration in parts of the brain. Possible signs are loss of appetite, weight loss, lack of energy, weakness, dizziness, lack of coordination, disorientation, tremors, and gradual paralysis. It has been suggested that nutritional deficiencies may worsen this disease because some sugar gliders appear to have improved when given Vitamin B1 (thiamine); however, the cause of this disease has not yet been determined. A severe case may prove deadly. A balanced and proper diet is most likely the best way to prevent this disease.
Toxoplasmosis is caused by a protozoan (microorganism) sometimes found in cat feces or in raw meat. Sugar gliders can get toxoplasmosis if they come into contact with cat litter or feces that have been contaminated with the parasite Toxoplasma gondii or if fed undercooked meats. Signs include lack of coordination, tremors, head tilt, diarrhea, loss of appetite and weight, loss of energy, below-normal body temperatures, trouble breathing, and sudden death. This parasite can also be passed to humans; the signs include fever, sore throat and muscles, and loss of vision. The parasite is particularly dangerous for pregnant women; infection can cause miscarriage or birth defects. People with weakened immune systems are also susceptible to becoming ill after contact with this parasite. To control this parasite, do not allow your sugar glider(s) to come in contact with a cat’s litter box, provide only thoroughly cooked meats, and use gloves and thorough hand washing when handling cat litter.
