Gerbil

Meriones unguiculatus

The pet gerbil is usually the Mongolian gerbil (Meriones unguiculatus), a small burrowing rodent from dry grassland and semi-desert habitats of Mongolia and northern China. It has a long furred tail, strong hind legs, and a social temperament shaped by life in family groups and tunnel systems. Domestic gerbils occur in many coat colors beyond the wild sandy agouti pattern, but their behavior still centers on digging, chewing, scent marking, and alert movement.

Good gerbil care starts with a secure tank or deep-sided enclosure that can hold a thick layer of bedding for tunnels. Pairs or stable same-sex groups often do well when introduced correctly, while careless mixing can lead to fighting. They need chew materials, sand baths, exercise space, and a seed-and-pellet diet balanced with small amounts of vegetables or forage. Tails should never be used for handling because the skin can slip. Breeders track family lines, color genetics, temperament, and age to avoid weak stock or overcrowding.
