About the Pet Mouse
Pet mice are active, scent-focused rodents that climb, dig, nest and explore through complex spaces. They are small but need much more than an empty starter cage.
Female mice usually benefit from compatible female company. Adult males often require different social arrangements because serious fighting can occur.
Health risks to know about
Common concerns include respiratory disease, tumours, skin parasites, wounds from fighting, dental problems and obesity.
Clicking or laboured breathing, a hunched posture, rapid weight loss, a growing lump or sudden isolation from the group needs veterinary attention.
Housing and daily setup
Use a secure, well-ventilated enclosure with deep burrowing bedding, nesting material, hides, tunnels, branches and a safe solid running wheel.
Check bar spacing and lids carefully. Avoid dusty bedding, scented products and open wire floors.
Food and water
Feed a complete mouse diet as the base with suitable fresh foods in small amounts. Scatter feeding encourages normal searching.
Provide clean water and monitor whether every mouse in a group can reach food and water.
Behaviour, company and enrichment
Burrowing, nesting, climbing and scent marking are normal. Rearrange only part of the setup at a time so some familiar routes and smells remain.
Use a tunnel or cupped hands for transfers. Never lift a mouse by the tail.
When to call an exotics vet
Get prompt help for breathing changes, collapse, seizures, major bleeding, a swollen abdomen, severe pain, inability to urinate or pass stool, or a sudden loss of balance or movement.
Small mammals often hide illness and can decline quickly. A clear change in appetite, droppings, breathing, movement or normal social behaviour deserves early veterinary advice.
