How long can you leave pet mice unattended?
You should not leave a mouse unattended outside it’s cage; this is dangerous as it could get injured, escape or be attacked by something (like another pet). Inside their cage, a mouse can be left unattended for any length of time as long as the cage is clean and the mouse has enough food and water. A mouse should not be left alone too long if it is by itself (in it’s cage) – mice are soical animals and therefore need the company of other mice.
