Gerbil at a glance
Gerbils are curious, friendly diggers that are awake more during the day than hamsters. They rarely bite, love to build tunnels, and are happiest living with a same-sex buddy.

Pet mice are tiny, active, and endlessly curious — fun to watch climb and explore. They are small and quick, so they suit gentle watching more than lots of handling. Female mice are social and like to live in small groups.
