Mice

Mouse care guide by SARI - Small Angels Rescue, Inc.

Domestic mice are intelligent and adorable pets and come in all kinds of colors. Related to the wild house mouse, domesticated mice have been bred as pets for centuries. They are social little creatures and love to have the companionship of other mice. However, unaltered male mice will likely fight if left together, so single male mice need a lot of attention from their human companions. Mice live on average 2 years, but they sure do pack a lot of life into that short time frame! Mice are difficult to handle for young children, but make great pets for adults and older children.
