|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Lean mouse-like body; visible tail; obesity shows as rounded abdomen |
| Daily Activity | 25 minutes |
| Caloric Notes | Base: 8-10 kcal/day; low-sugar diet essential |
| Litter Size | 4–7 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | Diabetes line screening |
| Neonatal Weight | 1.5–2 g |
|---|---|
| Growth Notes | Eyes open 12-14 days; weaning 21 days; sexually mature 8-12 weeks |
| Vaccine/Health Schedule | No standard vaccines |
| Temperature | 20-24°C (68-75°F) |
|---|---|
| Humidity | 40-60% |
| UVB Requirement | Not required |
| Diet | Low-sugar pellets, seeds, vegetables, occasional mealworms; avoid fruit |
| Common Issues | Diabetes, tumors, respiratory infections, tail degloving injuries |
| Anxiety Proneness | Medium |
|---|---|
| Top Triggers | Tail grabbing, sudden movements, cage mate introduction, small spaces without climbing options |
| Separation Anxiety Risk | Low |
| Calming Interventions | Vertical climbing space, consistent handling routine, multiple hideouts at different heights |
| Enrichment Needs | Climbing branches, rope bridges, multi-level habitat, foraging opportunities |
| Cognitive Dysfunction Risk | Low |
| Sociability Score | 2/10 |
| Locomotion | Climbing (prehensile tail assists), running, leaping between platforms |
|---|---|
| Social | Solitary preferred; same-sex pairs possible but risky; scent marking territory |
| Comfort | Self-grooming, stretching along branches, nest building |
| Stress/Displacement | Tail-slip (degloving) when grabbed by tail, freezing, aggression |
| Breed-Specific | Unique prehensile tail among hamsters; excellent climbers; mouse-like agility |
| Types | Squeaking (distress), ultrasonic social calls, chattering (annoyance) |
|---|---|
| Frequency Range | 3,000-50,000 Hz |
| Tendency | Low |
| Primary Modality | Scent marking primary; tail position secondary; vocalizations for distress |
| Tail/Body Signals | Prehensile tail used for balance - raised tail indicates alertness |
| Top Problems | Escape artistry (excellent climbers), tail-slip injuries, diabetes-related behavior changes |
|---|---|
| Medical Etiology | Diabetes causing excessive drinking/urination; tumor growth affecting mobility |
| Fear/Anxiety Etiology | Freezing, rapid climbing to highest point, tail-slip if grabbed |
| Frustration Etiology | Repetitive climbing patterns in small cages; bar chewing |
| Learned Behavior | Can learn to come to hand for food; relatively handleable with patience |
| Cognitive Dysfunction | Age-related activity decline; possible diabetes-related cognitive effects |
| AI-Trainable Signals | Tail position (raised=alert, wrapped=resting), climbing speed, body orientation on vertical surfaces |
|---|---|
| Context-Dependent Vocalizations | Rapid climbing may be exploration (relaxed body) or escape (tense body, flattened ears) |
| Interspecies Communication | Moderate handleability; recognizes handler; food-motivated interaction |
