|---|---|
| Grooming | Minimal - sand bath for coat; self-grooming species |
| Annual Exam Focus | Scent gland (ventral, tumor-prone), dental, nasal (allergic dermatitis), seizure history |
| Routine Care | Deep bedding (min 20cm for burrowing); sand bath; pair/group housing; fresh water; varied diet |
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Scent Gland Tumors | senior | high | Yes | Recommended |
| Epilepsy (Seizures) | juvenile | high | Yes | N/A |

| Tail Degloving | adult | medium | No | N/A |
| Stroke | senior | medium | No | N/A |
| Risk Level | Low |
|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Lean streamlined body; visible waist; active metabolism keeps weight stable |
| Daily Activity | 35 minutes |
| Caloric Notes | Base: 10-15 kcal/day; gerbil seed mix; limited sunflower seeds (high fat); vegetables |
| Litter Size | 3–8 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | Epilepsy line screening |
| Neonatal Weight | 2.5–3.5 g |
|---|---|
| Growth Notes | Eyes open 16-20 days; weaning 21-28 days; sexually mature 10-12 weeks; lifelong pair bonds |
| Vaccine/Health Schedule | No standard vaccines |
| Temperature | 20-24°C (68-75°F) |
|---|---|
| Humidity | 30-50% (desert-adapted) |
| UVB Requirement | Not required; diurnal species |
| Diet | Gerbil seed mix, pellets, fresh vegetables, occasional mealworms; low moisture diet (desert-adapted) |
| Common Issues | Scent gland tumors, seizures, nasal dermatitis, dental issues, tail degloving, stroke in elderly |
| Anxiety Proneness | Low |
|---|---|
| Top Triggers | Isolation, cage mate loss (declanning), sudden vibrations, predator scents |
| Separation Anxiety Risk | High |
| Calming Interventions | Bonded pair companion, deep burrowing substrate, consistent environment, sand bath |
| Enrichment Needs | Deep substrate for burrowing (20+ cm), cardboard tunnels to shred, sand bath, wheel, platforms |
| Cognitive Dysfunction Risk | Low |
| Sociability Score | 7/10 |
| Locomotion | Burrowing (primary), running, thumping hind feet (alarm), digging, sand bathing |
|---|---|
| Social | Pair-bonding species - MUST be kept in pairs minimum; mutual grooming; scent marking; foot thumping alarm |
| Comfort | Sand bathing, mutual grooming, side-by-side sleeping, relaxed digging |
| Stress/Displacement | Foot thumping (alarm), fighting (declanning), over-grooming, stereotypic digging |
| Breed-Specific | Prolific burrowers; foot-thumping communication; lifelong pair bonds; declanning devastating; desert-adapted |
| Types | Foot thumping, squeaking, purring/chirping, ultrasonic calls |
|---|---|
| Frequency Range | 1,000-50,000 Hz |
| Tendency | Low |
| Primary Modality | Foot thumping primary alarm; scent marking (ventral gland); body posture; ultrasonic for social |
| Tail/Body Signals | Tufted tail held up when alert; used for balance; NEVER grab by tail (degloving risk) |
| Top Problems | Declanning (sudden pair aggression), excessive digging, seizures |
|---|---|
| Medical Etiology | Seizures (handling-induced); scent gland tumors causing licking/bleeding; nasal dermatitis |
| Fear/Anxiety Etiology | Foot thumping, freezing, fleeing to burrow; rarely bites |
| Frustration Etiology | Stereotypic corner digging if substrate too shallow; bar chewing |
| Learned Behavior | Food-motivated; can learn to come to hand; handleable with gentle approach |
| Cognitive Dysfunction | Stroke risk in elderly; seizure-related cognitive effects |
| AI-Trainable Signals | Foot thumping pattern (rapid=alarm, slow=excitement), scent gland condition, pair proximity |
|---|---|
| Context-Dependent Vocalizations | Foot thumping during handling may be excitement or fear - body tension differentiates |
| Interspecies Communication | Friendly and curious toward humans; food-motivated bonding; pair bond with gerbil companion is priority |
