Sugar Glider Lecture

Sugar Glider Lecture

Scientific Classification

  • Latin Name: Cairis breviceps

  • Geographic Range:

    • Found in subtropical forested areas of:

    • Indonesia

    • New Guinea

    • Australia

Characteristics

  • Habitat:

    • Arboreal species - adept climbers.

  • Behavior:

    • Nocturnal - active during the night.

    • Considered a prey species - impacts behaviors.

    • Highly social animals, emphasizing the importance of appropriate housing.

  • Marsupial Traits:

    • Possess a pouch for young (joeys).

Pet Ownership Considerations

  • Legal Status in California: Sugar gliders are illegal to keep as pets.

  • Physical Parameters:

    • Weight:

    • Males: ~160 grams

    • Females: ~130 grams

    • Lifespan:

    • 10 to 14 years with optimal husbandry. Poor husbandry decreases lifespan.

    • Heart Rate:

    • 200 to 300 beats per minute (resting heart rate).

    • Respiratory Rate:

    • 16 to 40 breaths per minute.

    • Body Temperature:

    • 89°F to 96°F (variable range).

Reproductive Information

  • Gestation Period:

    • 15 to 17 days.

  • Joey Development:

    • Typically 1 to 2 joeys per birth.

    • Joey weight at birth: 2 to 3 grams.

    • Development in pouch: 70 to 74 days.

    • Full maturity reached between 6 to 8 months.

Behavioral Traits

  • Activity Patterns:

    • Nocturnal; daytime handling may lead to irritability.

  • Defense Mechanism:

    • If threatened, they stand on hind limbs and potentially charge.

  • Vocalization:

    • They produce distinct sounds such as barking and crabbing.

  • Social Bonding:

    • Typically bond closely with one person.

  • Aggression in Stressful Situations:

    • Increased aggression when distressed, particularly in clinical settings.

Unique Anatomical Features

  • Scent Glands:

    • Males have large scent glands on the head.

    • Females have additional glands in the pouch, chest, and around anus.

  • Eyes:

    • Large protruding eyes – susceptible to ocular injuries.

  • Genital Structure:

    • Males possess a bifurcated penis.

  • Tail:

    • Prehensile tail used for balance during gliding and climbing.

  • Digit Structure:

    • Opisthotonos digit (digit one) is opposable (syndactyly).

  • Pecten:

    • The flap of skin facilitating gliding.

Housing Requirements

  • Cage Type:

    • Well-ventilated, metal cages (coated to prevent toxicity).

  • Cage Size:

    • Minimum for two gliders: 18" x 18"; ideal: 6' x 6' x 6'.

    • Requires vertical space due to arboreal nature.

  • Temperature Zone:

    • Maintain between 75°F and 80°F.

    • Risk of torpor in lower temperatures.

  • Nest Boxes and Pouches:

    • At least one per glider, located high in the cage.

  • Feeding Stations:

    • Elevated water and food stations to avoid going to the cage floor.

  • Climbing Structures:

    • Use hardwood branches (maple, hickory, manzanita).

  • Toys:

    • Include exercise wheels and hanging toys designed for climbing.

  • Companion Animals:

    • Ideally housed in harems (one male to multiple females).

    • Do not house with cats (risk of toxoplasmosis) or rabbits (risk of Pasteurella).

  • Hazards in Household:

    • Supervised play necessary to avoid injuries (drowning, burns).

    • Awareness of toxins (e.g., scented products, rodent bait).

Nutrition

  • Feeding Habits:

    • Messy eaters, requiring regular cage cleaning (at least twice a week).

  • Water:

    • Clean, filtered water (avoid chloride sensitivity).

  • Cecum Function:

    • Enlarged cecum for nutrient fermentation (allows breakdown of complex sugars).

  • Diet Composition:

    • Spring/Summer: Mainly insectivores.

    • Winter: Consume gum, sap, and tree sugars.

  • Captive Diet:

    • 50% nectar and 50% insect diet.

    • Fruits and vegetables should constitute less than 10% of the diet, avoiding high sugars and fats.

    • Examples of nectar: powder mixed with water, honey.

    • Treats should mainly be insects, limited to prevent obesity.

    • Homemade Diet:

    • Leadbetter’s mixture - combines high protein baby cereal with nectar.

    • Commercial Options:

    • Wombaroo diet available for nutritional needs.

Restraint and Examination

  • Restraint Technique:

    • Hold head between thumb and middle finger (calm the animal first).

  • Exam Under Anesthesia:

    • Anesthetic gas used (often requires a mask similar to dogs).

    • Monitor for regurgitation during induction; suctioning may be required.

  • Physical Exam Details:

    • Evaluate limbs and toes; prone to self-mutilation.

    • Eye conditions: Keratitis (corneal inflammation) and uveitis (mid-eye inflammation).

  • Medication Administration:

    • Subcutaneous injections: preferably between scapula, avoiding pecten skin.

    • Intramuscular injections: lumbar or quadriceps muscles, taking care around nerves.

    • Blood collection typically done via jugular vein; minimize blood drawn (1% of body weight).

  • Radiographic Examination:

    • Requires anesthesia; DV positioning recommended for ease.

Medical Concerns

  • Nutritional Osteodystrophy:

    • Similar to metabolic bone disease; poor calcium and vitamin D leading to impairments. Progresses to hind limb paresis and fractures.

  • Obesity:

    • Caused by excessive treats and insects; require owner education.

  • Lumpy Jaw:

    • Caused by Actinomyces bacteria, leading to abscess formation in the jaw.

  • Trauma:

    • Common due to high activity and poor supervisions, leading to bite wounds.

  • Self-Mutilation:

    • Commonly occurs under stress, pain, and inadequate housing or nutrition.

  • Prolapses:

    • Rectal or cloacal prolapses may occur due to diarrhea or straining.

  • Castration:

    • Commonly performed; safe due to anatomy.

    • Spaying is avoided due to size; castration can be done with less anesthetic risk using lasers.

Conclusion

  • Overall considerations include appropriate husbandry practices, awareness of health risks, and understanding their unique physiological and behavioral needs.

  • Importance of an enriching environment for social interaction and physical activity is emphasized to ensure the well-being of sugar gliders in captivity.
