Pet mice are tiny, active, and endlessly curious — fun to watch climb and explore. They are small and quick, so they suit gentle watching more than lots of handling. Female mice are social and like to live in small groups.

Pet mice are tiny, curious, and active, especially at night. They're social, so females do best in small groups, and they live about 1.5–3 years.
✅ Before you bring a mouse home
🏠
Room at homeMice need a tank or fine-barred cage with deep bedding and things to climb, in a quiet, warm spot. They're escape artists, so the lid must be secure.
🛒
Supplies to get firstGet a secure cage or tank, deep bedding, a solid wheel, a water bottle, a food dish, hides, and safe chew toys.
🩺
Finding a vetFind an exotic or small-animal vet ahead of time. Mice are small and delicate, so handle gently and watch for sniffles or lumps.
💰
Money & emergenciesInsurance isn't practical for mice. Set aside a little emergency money for a vet visit if one gets sick.
