## Basic Information
| Field | Value |
|---|---|
| Species | Small Mammal |
| Origin | China/Mongolia |
| Size Category | Tiny |
| Scientific Name | Cricetulus griseus |
| Husbandry Difficulty | Intermediate |

## Vital Statistics
| Metric | Value |
|---|---|
| Weight Range | 0.03–0.045 kg |
| Lifespan | 2–3 years |
| Puppy/Kitten Stage Ends | 2 months |
| Senior Age Threshold | 2 years |

## Puppy/Kitten Development
- **Neonatal Weight**: 1.5–2 g
- **Growth Notes**: Eyes open 12-14 days; weaning 21 days; sexually mature 8-12 weeks
- **Vaccine Schedule**: No standard vaccines

## Adult Preventive Care
- **Exercise Needs**: High - agile climbers; need vertical space and wheel
- **Grooming**: Minimal; self-maintaining
- **Annual Exam Focus**: Diabetes screening, skin condition, dental check
- **Routine Care**: Climbing branches; deep bedding; fresh water; spot-clean daily

## Health Predispositions
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Diabetes Mellitus | adult | high | Yes | Yes |
| Skin Tumors | senior | medium | No | No |
| Respiratory Infections | adult | medium | No | No |
| Tail Injuries | adult | medium | No | No |

## Obesity Management
- **Risk Level**: Medium
- **Ideal BCS**: 3/9
- **Visual Cues**: Lean mouse-like body; visible tail; obesity shows as rounded abdomen
- **Daily Activity Target**: 25 minutes
- **Caloric Formula**: Base: 8-10 kcal/day; low-sugar diet essential

## Breeding & Genetics
- **Litter Size**: 4–7
- **Dystocia Risk**: Low
- **CHIC Required Tests**: N/A
- **Recommended DNA Tests**: Diabetes line screening

## Behavioral Ethogram
- **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

## Vocalization Baseline
- **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 Signals**: Prehensile tail used for balance - raised tail indicates alertness

## Emotional Wellbeing
- **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
- **Cognitive Dysfunction Risk**: Low

## Behavior Problems (Six-Etiology Classification)
- **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

## AI Communication Decoding
- **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

## Husbandry Environment
- **Temperature Gradient**: 20-24°C (68-75°F)
- **Humidity Range**: 40-60%
- **UVB Requirement**: Not required
- **Diet Type**: Low-sugar pellets, seeds, vegetables, occasional mealworms; avoid fruit
- **Common Health Issues**: Diabetes, tumors, respiratory infections, tail degloving injuries
