Important Gerbil vs. Hamster Differences for Pet Owners

Gerbils have long, furry tails and sleek bodies. Their hind legs are powerful, allowing them to stand upright and dig like champs. Hamsters—especially Syrian hamsters and dwarf hamsters—have chubby cheeks and short, stubby tails.

Hamsters come in multiple species with different colors and fur lengths (whereas pet gerbils are usually of a single species). Golden hamsters are one of the most popular. They tend to look rounder and puffier, with a stockier body shape.

This is a big one. Gerbils are highly social creatures that thrive in pairs or small groups. They need social interaction and can become stressed if kept alone.

Hamsters, however, are usually territorial. Most hamster species, especially Syrians, should be housed in separate cages to avoid fights with other hamsters.

Gerbils tend to interact more with humans and rarely bite. Hamsters are nocturnal, often sleeping during the day and becoming active at night. That can surprise new pet owners expecting daytime playtime.

Both animals need space, toys, and fresh water, but their housing differs. Gerbils love to dig and need deep bedding in a large cage. Cages often don’t provide enough room for their activity levels.

Hamsters, while also active, enjoy tunnels and wheel running. They don’t require as much digging depth but still need stimulation. Proper husbandry includes daily food checks and cage cleaning for both pets.

Pet gerbils and hamsters eat similar diets: grains, seeds, and small amounts of fruit or vegetables. Unlike guinea pigs, they don’t require added vitamin C. Just avoid sugary treats and make sure they always have clean water.

In terms of life span, hamsters usually live two to three years. Gerbils often reach three to four years with good care. Their longer lifespan and social nature can make gerbils better pets for families ready to commit.
