You’ve probably watched your hamster companion enjoying natural enrichment, and imagined them in the wild.

What if we hadn’t captured and calmed our fuzzy friends over 100 years ago?
What kind of lives would their wild ancestors have now?
How would their species have coped with human overdevelopment, conflict, intensive farming?
The UK has never had any wild hamsters. The species we keep as companions don’t survive the UK climate and ecosystem; escapees and abandoned pets face death before they can breed.
But in mainland Europe, there’s a hamster tough enough to make it in an often colder, wetter, less overbuilt landscape.
And we adore them, but fear for their future.
The European Hamster: Big, bolshy and on the edge of extinction
If you love hamsters, it’s impossible not to love the EU Zone’s only indigenous wild hamster species. Cricetus cricetus, as the scientific name suggests, is one of a kind.

Twice as big as the next-largest hamster species (the Syrian hamster), European hamsters are the size of a guinea pig or large squirrel.
Wherever they’ve crossed paths with other wild hamsters - the Romanian hamster and the Georgian hamster to the south and east of their range - they’ve historically done better due to their size, and very bad temper!

European hamsters are incredibly cute, but they are definitely not domesticable!
Ferocious defenders of territory and mating rights, they’ll take on any perceived threat with fearless aggression, and can successfully chase off much larger animals with their frankly scary displays.
All hamsters are burrowers, and hoarders. European hamsters do this on a grand scale: we’ve found burrows up to 5 metres deep and stretching over 500 metres!
European hamsters have also kept their ability to hibernate healthily, where other hamster species have devolved it. They store vast quantities of food, fending off burrow invaders and rivals of their own species who try to steal their stashes.

Conservation breeding programmes have found European hamsters remain aggressive in captivity, and actively seek to escape using all sorts of smart tactics.

Once king of the fields across the entire of central and eastern Europe, the last 50 years has seen a terrible decline. They are now classified as “Critically Endangered”.
How could humans have caused so much damage so fast?
Adapted to the steppes of undeveloped Europe, for millennia European hamsters lived mostly undisturbed. As humans converted the landscape for crops, they adapted and thrived as many of their natural predators were hunted to local extinction. A rich diet, tilled soil for their complex burrows, and a huge gene pool kept the species healthy.
Since World War 2 the intense use of pesticides, and persecution by farmers have been huge factors in their terrifying decline, alongside crop monocultures - huge areas of farmland growing only one strain of only one crop (like maize) to meet human demand and maximise profits.
Herbicides are almost as much of a problem: the “weeds” that grow between and amongst human crops are staple foods for the European hamster.
Hamsters need a varied diet, and their population health declines if all they have to eat is one type of food.
With corporate agriculture actively poisoning them as pests, and survival rates damaged by malnutrition, massive damage was done before the EU stepped in, even threatening France with fines in the millions for failing to protect the species.

Many European countries where cricetus once thrived now have captive breeding and reintroduction programmes, but safe land is hard to find, and the released hamsters face the same battles for survival as their remaining freeborn relatives.
The Gravediggers
Famously, a pocket of 70-100 European hamsters has found an urban sanctuary in the Central Cemetery in Vienna.
Thriving in the untended grasslands of the huge graveyard, scavenging what human visitors leave behind - even candle wax! - they’re a common sight at dusk, and thousands of hamster fans and wildlife enthusiasts visit annually for a glimpse of them going about their business.
