|---|---|
| Lifespan | 10–15 years |
| Juvenile Stage Ends | 6 months |
| Senior Age Threshold | 10 years |
| Exercise Needs | Very High - nocturnal gliders need large tall cage and nightly out-of-cage time |
|---|---|
| Grooming | Minimal - self-grooming; check patagium (gliding membrane) for tears |
| Annual Exam Focus | Nutritional status (calcium:phosphorus ratio critical), dental, patagium condition, weight, cloaca |
| Routine Care | Specialized diet (calcium-balanced); nightly bonding time; large cage cleaning; colony management |
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Nutritional Osteodystrophy (Metabolic Bone Disease) | adult | very high | No | N/A |
| Obesity | adult | high | No | N/A |
| Self-Mutilation | adult | high | No | N/A |
| Stress-Related Disease | adult | high | No | N/A |
| Dental Disease | adult | medium | No | Recommended |
| Parasites | adult | medium | No | N/A |
| Risk Level | High |
|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Patagium should be thin membrane; fat deposits visible along body indicate obesity |
| Daily Activity | 60 minutes |
| Caloric Notes | Specialized diet required (BML, TPG, or similar); calcium:phosphorus ratio 2:1; limit sugary fruits |
| Litter Size | 1–2 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | Inbreeding coefficient assessment |
| Neonatal Weight | 0.2–0.5 g |
|---|---|
| Growth Notes | Marsupial - joey born undeveloped, crawls to pouch; in-pouch 60-70 days; out-of-pouch (OOP) at 8-10 weeks; weaning 12-16 weeks |
| Vaccine/Health Schedule | No standard vaccines |
| Temperature | 21-27°C (70-80°F) |
|---|---|
| Humidity | 40-60% |
| UVB Requirement | Not required; nocturnal; 12:12 light cycle |
| Diet | SPECIALIZED: BML/TPG/Critterlove diet (calcium-balanced); fresh fruits/vegetables; insects; NO cat food/dog food; calcium:phosphorus ratio critical |
| Common Issues | Metabolic bone disease (improper diet), self-mutilation (loneliness/stress), obesity, dental disease, stress-related illness |
| Anxiety Proneness | High |
|---|---|
| Top Triggers | Isolation (single housing), daytime disturbance, unfamiliar scents, separation from bonded colony |
| Separation Anxiety Risk | Very High |
| Calming Interventions | Colony housing (mandatory), bonding pouch (carrying during day), consistent routine, familiar scents |
| Enrichment Needs | Tall cage with branches, foraging opportunities, gliding space, bonding pouch time, varied diet presentation |
| Cognitive Dysfunction Risk | Medium |
| Sociability Score | 9/10 |
| Locomotion | Gliding (patagium spread), climbing, leaping, crabbing (defensive posture with arms spread) |
|---|---|
| Social | Obligate social species - MUST be kept in pairs/colonies; mutual grooming; sleeping in groups; colony scent marking |
| Comfort | Communal sleeping in pouch, mutual grooming, soft chirping, relaxed gliding |
| Stress/Displacement | Crabbing (loud defensive sound), self-mutilation, over-grooming, biting, excessive barking at night |
| Breed-Specific | Marsupial with gliding membrane; obligate social species; nocturnal; specialized diet requirements; bonds intensely with colony/owner; illegal in some jurisdictions |
| Types | Crabbing (loud defensive buzzing), barking (attention/loneliness), chirping (contentment), hissing (annoyance), purring (pleasure) |
|---|---|
| Frequency Range | 1,000-20,000 Hz |
| Tendency | High |
| Primary Modality | Vocalizations very important; scent marking (males have head/chest glands); body posture; gliding membrane position |
| Tail/Body Signals | Prehensile tail used for balance and carrying; tail position indicates mood (curled=relaxed, straight=alert) |
| Top Problems | Self-mutilation (from loneliness), nocturnal barking, biting during taming, dietary deficiency behaviors |
|---|---|
| Medical Etiology | Metabolic bone disease causing fractures/paralysis; self-mutilation wounds; dental pain |
| Fear/Anxiety Etiology | Crabbing, biting, lunging, spreading patagium to appear larger |
| Frustration Etiology | Nocturnal barking (loneliness/boredom), cage pacing, self-harm |
| Learned Behavior | Bonds intensely with patient owner; pouch-trained; responds to voice; colony acceptance of human |
| Cognitive Dysfunction | Long-lived - possible age-related decline after 10+ years |
| AI-Trainable Signals | Vocalization type (crabbing=fear, barking=lonely, chirping=happy), patagium position, tail curl, scent marking frequency |
|---|---|
| Context-Dependent Vocalizations | Nocturnal barking may be loneliness (needs companion) or communication (normal colony behavior) - housing context critical |
| Interspecies Communication | Bonds very deeply with dedicated owner (becomes part of "colony"); requires significant time investment; carries owner scent for comfort |
