Mouse Adoption tools: what they help with

These tools help you decide whether a mouse fits your life right now, with readiness quizzes and checklists for the first weeks at home. Thinking it through before adopting is the best way to make sure a new pet stays for good.

What to know about adoption readiness for mice

Mice typically live 1.5 to 3 years. Mice need a secure tank or narrow-bar cage with deep bedding for burrowing and plenty of climbing height. Females live well in groups; males usually must be housed alone to avoid fighting.
