# African Pygmy Hedgehog

> According to allpets.ai data | Source: allpets.ai

## Basic Information
| Field | Value |
|---|---|
| Species | Small Mammal |
| Origin | Central/East Africa |
| Size Category | Tiny |
| Scientific Name | Atelerix albiventris |
| Husbandry Difficulty | Intermediate |

## Vital Statistics
| Metric | Value |
|---|---|
| Weight Range | 0.3–0.6 kg |
| Lifespan | 3–6 years |
| Puppy/Kitten Stage Ends | 3 months |
| Senior Age Threshold | 3 years |

## Puppy/Kitten Development
- **Neonatal Weight**: 8–18 g
- **Growth Notes**: Born with membrane-covered quills; first quilling at 6-8 weeks (grumpy period); adult quills by 12 weeks; mature at 6 months
- **Vaccine Schedule**: No standard vaccines

## Adult Preventive Care
- **Exercise Needs**: High - needs wheel (solid surface, min 30cm) and exploration time nightly
- **Grooming**: Low - occasional foot bath (running on wheel dirties feet); nail trims; no quill brushing
- **Annual Exam Focus**: Skin/quill condition (mites common), weight (obesity epidemic), oral exam, tumor screening
- **Routine Care**: Nightly wheel access; warm environment (24-27°C); insect-based diet; foot baths; regular weight checks

## Health Predispositions
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Obesity | adult | very high | No | No |
| Cancer (various types) | senior | very high | Yes | No |
| Wobbly Hedgehog Syndrome (WHS) | adult | high | Yes | No |
| Skin Mites | adult | high | No | No |
| Dental Disease | adult | high | No | Yes |
| Fatty Liver Disease | adult | medium | No | No |

## Obesity Management
- **Risk Level**: Very High
- **Ideal BCS**: 3/9
- **Visual Cues**: Should be able to curl into tight ball; if cannot fully curl = obese; no fat rolls around legs
- **Daily Activity Target**: 40 minutes
- **Caloric Formula**: Low-fat cat kibble or hedgehog food (max 15% fat); insects as treats only; strict portion control

## Breeding & Genetics
- **Litter Size**: 2–5
- **Dystocia Risk**: Medium
- **CHIC Required Tests**: N/A
- **Recommended DNA Tests**: WHS carrier screening (limited availability)

## Behavioral Ethogram
- **Locomotion**: Wheel running (primary exercise), exploring, anointing (self-anointing with new scents/foamy saliva)
- **Social**: Solitary species - must be housed alone; tolerates human handling with habituation
- **Comfort**: Relaxed quills (flat), exploring with nose down, anointing (positive response to new stimuli)
- **Stress/Displacement**: Balling up, hissing, popping/clicking, quill erection, green stress poop
- **Breed-Specific**: Self-anointing behavior (unique); nocturnal; solitary; quill defense system; prone to obesity and cancer; "grumpy" during quilling periods

## Vocalization Baseline
- **Types**: Huffing/puffing (annoyance), hissing (threat), popping/clicking (defensive), purring (contentment), screaming (extreme pain)
- **Frequency Range**: 500-10,000 Hz
- **Tendency**: Low
- **Primary Modality**: Quill position primary (flat=relaxed, erect=defensive); body posture (balled=scared); vocalizations secondary
- **Tail Signals**: Very short tail - no signaling function

## Emotional Wellbeing
- **Anxiety Proneness**: High
- **Top Triggers**: Bright lights, sudden noises, unfamiliar scents, being woken during day, cold temperatures
- **Separation Anxiety Risk**: Low
- **Calming Interventions**: Consistent handling routine, warm fleece bonding pouch, familiar scents (worn t-shirt), dim lighting
- **Cognitive Dysfunction Risk**: Low

## Behavior Problems (Six-Etiology Classification)
- **Top Problems**: Balling up during handling, biting (rare but possible), obesity-related inactivity, hibernation attempts
- **Medical Etiology**: WHS causing progressive paralysis; cancer causing lumps/behavioral changes; dental pain causing food refusal
- **Fear/Anxiety Etiology**: Balling up (primary defense), hissing, popping quills; rarely bites unless extreme
- **Frustration Etiology**: Limited expression; may become more defensive if handling is inconsistent

## AI Communication Decoding
- **AI-Trainable Signals**: Quill position (flat=calm, semi-raised=cautious, fully erect=defensive), nose activity (sniffing=curious), body curl degree
- **Context-Dependent Vocalizations**: Self-anointing (foamy mouth, contorting body) is NORMAL positive behavior, not seizure or illness
- **Interspecies Communication**: Bonds with patient handlers through scent familiarity and consistent routine; not affectionate in traditional sense but develops trust

## Husbandry Environment
- **Temperature Gradient**: 24-27°C (75-80°F) CRITICAL - hibernation attempt below 20°C can be fatal in captivity
- **Humidity Range**: 40-60%
- **UVB Requirement**: Not required; nocturnal; consistent 12-14 hour light cycle prevents hibernation attempts
- **Diet Type**: Low-fat high-protein kibble (cat food or hedgehog-specific); insects (mealworms, crickets) as treats; occasional fruits/vegetables
- **Common Health Issues**: Obesity (most common), cancer (extremely high rate after age 3), WHS, mites, dental disease, hibernation attempts, fatty liver
