## Basic Information
| Field | Value |
|---|---|
| Species | Small Mammal |
| Origin | Syria |
| Size Category | Tiny |
| Scientific Name | Mesocricetus auratus |
| Husbandry Difficulty | Beginner |

## Vital Statistics
| Metric | Value |
|---|---|
| Weight Range | 0.1–0.2 kg |
| Lifespan | 2–3 years |
| Puppy/Kitten Stage Ends | 3 months |
| Senior Age Threshold | 2 years |

## Puppy/Kitten Development
- **Neonatal Weight**: 2–3 g
- **Growth Notes**: Eyes open at 14 days; weaning at 21-28 days; sexually mature at 6-8 weeks
- **Vaccine Schedule**: No standard vaccines; focus on clean environment and quarantine of new animals

## Adult Preventive Care
- **Exercise Needs**: Moderate - daily wheel running (8-12 km/night typical); supervised free-roam time 15-30 min daily
- **Grooming**: Minimal for short-haired; long-haired variants need weekly brushing
- **Annual Exam Focus**: Dental check (malocclusion), skin/fur condition, cheek pouch inspection, weight monitoring
- **Routine Care**: Spot-clean cage daily; full bedding change weekly; fresh water daily; varied diet with pellets, seeds, vegetables

## Health Predispositions
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Wet Tail (Proliferative Ileitis) | juvenile | high | No | No |
| Dental Malocclusion | adult | medium | Yes | Yes |
| Cheek Pouch Impaction | adult | medium | No | No |
| Skin Mites (Demodex) | adult | medium | No | No |
| Diabetes Mellitus | adult | low | Yes | No |
| Amyloidosis | senior | medium | No | No |

## Obesity Management
- **Risk Level**: Medium
- **Ideal BCS**: 3/9
- **Visual Cues**: Visible waist when viewed from above; ribs palpable with slight fat cover; no excessive fat deposits around limbs
- **Daily Activity Target**: 30 minutes
- **Caloric Formula**: Base: 12-15 kcal/day for 120-150g hamster; adjust ±10% based on activity level

## Breeding & Genetics
- **Litter Size**: 6–12
- **Dystocia Risk**: Low
- **CHIC Required Tests**: N/A
- **Recommended DNA Tests**: N/A

## Behavioral Ethogram
- **Locomotion**: Wheel running, burrowing, climbing, pouching food for transport
- **Social**: Strictly solitary as adults; territorial aggression toward conspecifics; scent marking
- **Comfort**: Grooming, stretching, yawning, nest building with substrate
- **Stress/Displacement**: Bar chewing, excessive grooming, cage climbing, freezing, aggression
- **Breed-Specific**: Extensive food hoarding in cheek pouches; deep burrowing; nocturnal/crepuscular activity pattern

## Vocalization Baseline
- **Types**: Squeaking (distress/excitement), hissing (threat), clicking (contentment), ultrasonic calls
- **Frequency Range**: 2,000-50,000 Hz (includes ultrasonic)
- **Tendency**: Low
- **Primary Modality**: Primarily scent-based (flank glands); body posture secondary; vocalizations tertiary
- **Tail Signals**: Vestigial tail - no significant signaling function

## Emotional Wellbeing
- **Anxiety Proneness**: Medium
- **Top Triggers**: Sudden loud noises, cage disturbance during sleep, unfamiliar scents, bright lights
- **Separation Anxiety Risk**: Low
- **Calming Interventions**: Deep bedding for burrowing, hideouts, consistent routine, dim lighting during active hours
- **Cognitive Dysfunction Risk**: Low

## Behavior Problems (Six-Etiology Classification)
- **Top Problems**: Bar chewing, escape attempts, aggression during handling, food guarding
- **Medical Etiology**: Pain from dental issues causing irritability; skin parasites causing excessive scratching
- **Fear/Anxiety Etiology**: Biting when startled; freezing in open spaces; nocturnal hyperactivity if disturbed during day
- **Frustration Etiology**: Bar chewing and cage climbing from inadequate space (<4000 cm² floor); wheel deprivation

## AI Communication Decoding
- **AI-Trainable Signals**: Ear position (forward=curious, flat=fearful), body posture (upright=alert, hunched=stressed), cheek pouch fullness
- **Context-Dependent Vocalizations**: Squeaking during handling may indicate pain OR excitement - context of body tension differentiates
- **Interspecies Communication**: Limited interspecies communication; relies on scent recognition of handler; habituation-based trust

## Husbandry Environment
- **Temperature Gradient**: 20-24°C (68-75°F)
- **Humidity Range**: 40-60%
- **UVB Requirement**: Not required; natural room light cycle 12:12
- **Diet Type**: Commercial hamster pellets supplemented with fresh vegetables, occasional protein (mealworms, boiled egg)
- **Common Health Issues**: Wet tail, respiratory infections, dental overgrowth, skin mites, hibernation risk below 15°C
