Mice

Mice are active and social animals with extreme curiosity. They are considered to be great pets due to their entertaining antics and rather affectionate behavior. Despite what most people may think, mice are actually very clean animals that organize their habitat into areas for eating, sleeping, bathroom needs, etc.

Mice are adorable

They enjoy the company of other mice and can be kept together in same-sex groups. One of the best things you can provide for a mouse is an exercise wheel; it will never go unused. In addition, like other small animals, a mouse's teeth grow continuously throughout their life so they should be provided with chew sticks to prevent teeth from becoming over-grown. Mice should never be picked up by their tail. Gently scooping them up and daily handling them will allow you to build a trusting bond with your mice, giving you the opportunity to see their true personality shine!
