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!
