| Size Category | Tiny |
| Scientific Name | Phodopus sungorus |
| Category | Rodent |
| Original Purpose | Companion |
| Husbandry Difficulty | Beginner |
| Social Needs | Low |
| Weight Range | 0.03–0.045 kg |
|---|---|
| Lifespan | 1–3 years |
| Juvenile Stage Ends | 2 months |
| Senior Age Threshold | 2 years |
| Exercise Needs | Moderate - wheel running essential; smaller body means proportionally high activity |
|---|---|
| Grooming | Minimal; self-grooming species; sand bath provided for coat maintenance |
| Annual Exam Focus | Weight monitoring (diabetes-prone), dental check, foot pad inspection |
| Routine Care | Fresh water daily; spot-clean; full cage clean every 5-7 days; monitor food intake for diabetes signs |
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Diabetes Mellitus | adult | high | Yes | Recommended |
| Obesity | adult | high | Yes | N/A |
| Dental Malocclusion | adult | medium | Yes | Recommended |
| Skin Tumors | senior | medium | No | N/A |
| Respiratory Infections | adult | medium | No | N/A |
| Risk Level | High |
|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Pear shape indicates obesity; should maintain oval body shape; ribs palpable |
| Daily Activity | 20 minutes |
| Caloric Notes | Base: 8-10 kcal/day; strictly limit sugary treats; avoid fruit |
| Litter Size | 4–8 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | Diabetes susceptibility line testing |
| Neonatal Weight | 1–2 g |
|---|---|
| Growth Notes | Eyes open 12-14 days; weaning 18-21 days; mature at 5-6 weeks; coat color change with photoperiod |
| Vaccine/Health Schedule | No standard vaccines |
| Temperature | 18-22°C (65-72°F); coat turns white below certain photoperiod |
|---|---|
| Humidity | 40-55% |
| UVB Requirement | Not required; photoperiod affects coat color (shorter days = white coat) |
| Diet | Low-sugar pellets, seeds, vegetables; AVOID fruit and sugary treats due to diabetes risk |
| Common Issues | Diabetes, obesity, respiratory infections, dental problems, skin tumors |
| Anxiety Proneness | Medium |
|---|---|
| Top Triggers | Sudden handling, cage mate conflict, temperature drops, unfamiliar environment |
| Separation Anxiety Risk | Low |
| Calming Interventions | Consistent routine, deep bedding, multiple hideouts, sand bath access |
| Enrichment Needs | Foraging puzzles, varied substrates, tunnels, wheel (min 20cm diameter) |
| Cognitive Dysfunction Risk | Low |
| Sociability Score | 3/10 |
| Locomotion | Wheel running, tunneling, quick darting movements, sand bathing |
|---|---|
| Social | Can cohabitate same-sex pairs if introduced young; mutual grooming; sleeping huddles |
| Comfort | Sand bathing, self-grooming, nest building, stretching |
| Stress/Displacement | Freezing, rapid breathing, aggression toward cage mate, excessive hiding |
| Breed-Specific | Photoperiod-responsive coat color change; torpor in cold; food caching behavior |
| Types | Ultrasonic calls, squeaking (distress), chattering (aggression) |
|---|---|
| Frequency Range | 5,000-45,000 Hz |
| Tendency | Low |
| Primary Modality | Scent marking (ventral gland); body posture; ultrasonic for social communication |
| Tail/Body Signals | Very short tail - minimal signaling |
| Top Problems | Cage mate aggression, diabetes-related lethargy, escape attempts |
|---|---|
| Medical Etiology | Diabetes causing polydipsia/polyuria and behavioral changes; dental pain causing food avoidance |
| Fear/Anxiety Etiology | Freezing and playing dead; biting when cornered |
| Frustration Etiology | Small cage syndrome - repetitive behaviors, bar chewing |
| Learned Behavior | Hand-shy behavior from improper handling; food-associated approach behavior |
| Cognitive Dysfunction | Limited data; age-related activity decline |
| AI-Trainable Signals | Body shape (round=relaxed, elongated=alert/fearful), ear position, whisker orientation |
|---|---|
| Context-Dependent Vocalizations | Squeaking can indicate play (with cage mate) or distress (when handled) - social context matters |
| Interspecies Communication | Habituates to handler scent; can distinguish familiar vs unfamiliar humans by smell |
