Spiny Mouse Care Sheet

Origin:

Spiny mice (Acomys spp.) are small rodents native to arid regions of Africa and the Middle East. They inhabit rocky deserts and scrublands, often sheltering in crevices and burrows.

Description:

Spiny mice are named for the stiff, spiny hairs on their backs. They have a body length of 3–5 inches and weigh 20–50 grams. Their tails are slightly shorter than their body length. They are nocturnal or crepuscular and have an average lifespan of 3–5 years in captivity.

Temperament:

Spiny mice are curious, active, and social. They can be handled carefully but are faster and more fragile than typical pet mice. They prefer to live in groups and benefit from social interaction and environmental enrichment.

Feeding:

• Staple diet: High-quality rodent pellets or small rodent diet.
• Vegetables: Leafy greens, carrots, and squash in small amounts.
• Fruits: Small portions of apple, pear, or berries occasionally.
• Protein: Mealworms or cooked egg bits occasionally.
• Water: Fresh, clean water provided daily.

Avoid sugary or fatty human foods and limit seeds to prevent obesity.

Housing:

• Cage type: Glass or wire enclosure with solid flooring; escape-proof.
• Size: Minimum 12"x12"x12" for a small group; provide climbing structures.
• Bedding: Paper-based bedding, soft hay, or shredded paper; avoid cedar or pine shavings.
• Temperature: 72–80°F; avoid drafts or extreme heat.
• Accessories: Rocks, tunnels, hiding boxes, and branches for climbing and exploration.
• Cleaning: Spot clean daily and fully clean weekly.

Companionship:

Spiny mice are social and do best in small groups of same-species mice. Monitor for aggression during introductions and provide multiple shelters to reduce territorial disputes.

Handling:

Handle gently using cupped hands. Avoid squeezing or rough handling due to their delicate skin and tails. Spend short, consistent periods handling to build trust.

Health:

Common health issues include:

• Obesity from overfeeding or improper diet
• Skin injuries or infections from fighting or sharp objects
• Respiratory infections from poor ventilation or damp bedding

Provide proper diet, a clean environment, and regular checkups with an exotic animal veterinarian.

Grooming:

Spiny mice groom themselves frequently. Offer clean bedding and nesting materials to support natural grooming. External baths are rarely necessary and may cause stress.

Fun Facts:

• Spiny mice can shed skin along their back as a defense mechanism to escape predators.
• They are excellent jumpers and climbers despite their small size.
• Spiny mice communicate using squeaks, chirps, and other vocalizations.
• They are mostly nocturnal or crepuscular, active during dawn and dusk.
