Rat 101

Rats are omnivores (and not very picky ones). They have terrible vision, and they're colorblind, so they rely on their fine sense of smell and whiskers for touch. They have some very talented teeth: rats can chew through wood, metal, even concrete (if uncured). They're also highly social, enjoying play and cuddling with other rats. They develop deep bonds with their rat pack, and if a member of the group becomes sick they will care for it. A lonely rat is an unhealthy rat – it will quickly develop anxiety and depression.
