Sugar Gliders

The sugar glider is native to eastern and northern mainland Australia, and was introduced to Tasmania. The sugar glider is also native to various islands in the region.

• Sugar glider (Petaurus breviceps)
• Tree-dwelling, nocturnal marsupial from Australia and New Guinea
• Diet during the spring and summer months consists almost entirely of insects and other prey items; diet during the fall and winter consists of eucalyptus sap, acacia gum, nectar, and manna (sap that oozes from wounds on trees)
• Live in large family groups (colonies) of 15-30 individuals
• Males have a scrotal sac located on the abdomen, where you would expect the belly button to sit; it looks like a little pom-pom.  They also have a bifurcated (forked) penis.  At maturity, intact males develop oily bald spots (scent glands) on their forehead and chest.  Neutering prevents this.
• Females have a “U”-shaped opening on the abdomen, where you would expect the belly button to sit.  This opens into the pouch (marsupium) where the babies develop and contains two teats.

Behavior

• Extremely social animals, best kept in groups of 2 or more
• Solitary gliders require a lot of attention from their owners!
• Prone to behavioral problems if housed alone
• Best time to adopt/socialize is when joeys are 7-12 weeks out of pouch
• Very vocal: “crabbing” when excited, “bark” or “chatter” for attention
• Scent marking behavior allows recognition by group members
• Intact males mark their cages with urine.  Neutering reduces this tendency.
• Breed readily in captivity

Diet

• BML (recipe below) or commercial diet for insectivore/carnivore (e.g. cat food kibble)
• Need fresh fruits and vegetables (NOT canned, dried, or trail mix) such as chopped apple, mango, grape, carrot, sweet potato, etc.
• Heavily insectivorous – supply gut loaded crickets, mealworms, waxworms, moths
• Require ~50% protein in diet supplied by insects, lean boiled chicken or turkey, scrambled egg, cottage cheese, yogurt
• Fresh foods and insects can be dusted with mineral supplements such as Repcal or Herptivite, supplements such as Glideraide, Supreme blend, or Lory nectar may also be offered

Environment

• Because of their social nature, pet gliders should always be kept in pairs or small groups.  Fighting is rare; same- or mixed-gender groups are usually fine.
• Require large cages (minimum 2 cubic feet, should be as large as possible)
• Wire caging best with mesh size no larger than ½” to ¾”
• Require non-toxic branches (manzanita, apple, citrus) for perching, chewing, exercise
• Need pouches or nest boxes near the top of the enclosure for resting, hiding
• Use aspen or paper bedding – avoid cedar and pine as these can cause respiratory problems
• Environment should be draft free, 70-90°F (21.1-32.2°C), NOT placed in bright sunlight!
• Keeping the cage/bedding very clean will help prevent odor and behavioral problems such as self-barbering and self-mutilation

Preventive Care

• Routine physical examination every 6 to 12 months
  • Consult a veterinarian with experience treating exotic pets if you have any questions or concerns about your sugar glider’s health.
  • Annual fecal examination for parasites
  • Blood tests as recommended by your veterinarian
  • Neutering males prevents development of prominent scent glands
  • Toenails require regular trimming
  • No vaccines are required

Common Medical Disorders

• Malnutrition and its consequences
  • Hind limb paralysis, tremors, rickets, cataracts, blindness
  • Stress-related diseases
    • Self-mutilation, pulling or chewing fur, pacing, eating disorders, cannibalism of young, abnormal aggression
  • Pneumonia
  • Diarrhea
  • Internal parasites
