The Hamster Encyclopedia

An affectionate, slightly unserious reference work. Real facts, lightly seasoned with nonsense, edited by our resident specimen, Mr. Tofu Ciabatta.

1. What is a hamster?

A hamster is a rodent of the subfamily Cricetinae. There are about eighteen species, from the palm-sized Roborovski to the Syrian, the classic pet-shop hamster. The word hamster comes from the German hamstern, meaning to hoard, which tells you everything you need to know about their priorities.

Did you know? A hamster's very name literally means "hoarder". The animal was named after its hobby.

2. Species guide

Five species do most of the pet-keeping. Syrians are the big, fluffy classic; the dwarfs are smaller, faster, and considerably more opinionated per gram.

SpeciesSizeTemperament
Syrian (golden)About 15 cmSolitary; must live alone
Campbell's dwarfAbout 10 cmSocial, but nippy when young
Winter White dwarfAbout 10 cmCalm; coat whitens in winter
Roborovski dwarfAbout 5 cmThe fastest; prefers watching to cuddling
Chinese10–12 cm, long tailA climber; the only common species with a real tail

3. Cheek pouches

A hamster's cheek pouches are stretchy pockets that run back to the shoulders. They are not for chewing, they are for carrying: a hamster can stuff them so full that its head looks twice as wide, then waddle home and unpack everything into a secret pantry. Our specimen's own policy is strict. Carrots are collectible. Everything nut-shaped is an obstacle, and airborne nuts at carrot height are to be run under, never jumped into.

4. Teeth that never stop

A hamster's front teeth grow continuously throughout its life. In the wild they are worn down by gnawing seeds, stems and the occasional enclosure fixture. Give a hamster nothing to chew and its teeth will overgrow, which is why a hamster's home should always contain something legal to destroy.

5. The wheel

In the wild, a Syrian hamster may cover eight kilometres in a single night of foraging. The exercise wheel is the pet hamster's answer to that commute. Our specimen, Mr. Tofu Ciabatta, holds a personal best of 3,273 rotations in one night (9 October), about 2.9 kilometres on his wheel. His wheel is occasionally closed for maintenance, at which point he is expected to be furious.

6. Burrows and hoarding

Wild hamsters dig burrows up to two metres deep, with separate chambers for sleeping, nesting and, most importantly, food. A single wild pantry can hold tens of kilograms of grain, gathered one cheek-load at a time. At home, the same instinct produces a hamster who hides food in every corner and then looks at you as if to ask: what food?

Did you know? A Syrian hamster's burrow can be over ten times its own body length deep. The pantry is the point of the whole operation.

7. Sleep and the night shift

Hamsters are nocturnal, or more precisely crepuscular: busiest at dawn and dusk, asleep for most of the day. A hamster woken mid-nap is a grumpy hamster. After his 1,594-rotation night of 23 October, Mr. Tofu Ciabatta was officially recorded as tired and irritable, and declined a morning carrot without enthusiasm. The record stands as a warning to all wheels.

8. A short history

Pet hamsters descend from a single litter found in Syria in 1930. A zoologist collected a mother and her pups, and almost every Syrian hamster kept since is descended from that family. From a Syrian field to a wheel in Prague in under a century: a remarkable career, and one this encyclopedia's editor takes personally.

9. Field notes: the explorer

In the wild, hamsters are explorers of steppe and farmland, navigating by smell and whisker more than by sight: their eyesight is poor, their noses excellent, and their whiskers do much of the steering. Chib's own expeditions are usually accompanied by his brick-built twin, who has never once complained about the pace.

Did you know? Hamsters see poorly but smell superbly. If a hamster stares at you blankly, it has probably already identified you by scent and moved on.
