# Ferret — Facts, Threats & Conservation

*Mustela furo*

> A ferret (Mustela furo) is a domesticated member of the weasel family, bred from the European polecat about 2,500 years ago. Long-bodied, playful and carnivorous, it has long been used to hunt rabbits and is today a popular household pet, typically living seven to ten years.

**IUCN status:** Domesticated; not a threatened species  ·  **WARN range:** Worldwide (as a domestic pet and working animal), Europe, North America, Australia and New Zealand

## Scientific classification
- **Kingdom:** Animalia
- **Phylum:** Chordata
- **Class:** Mammalia
- **Order:** Carnivora
- **Family:** Mustelidae
- **Genus:** Mustela
- **Species:** Mustela furo

## Conservation status
- **Status:** The domestic ferret (Mustela furo) is a domesticated animal and is not assessed on the IUCN Red List; it has no wild population requiring conservation. By contrast, the separate black-footed ferret (Mustela nigripes) of North America is classified as Endangered, and the wild ancestor of the domestic ferret, the European polecat (Mustela putorius), is listed as Least Concern.
- **Population:** Not assessed as a wild species; kept as a pet and working animal worldwide, with several million in the United States alone.
- **Trend:** Not applicable (domesticated); pet populations are stable to common.
- **Assessed:** Not assessed (domesticated species)
- **CITES:** Not listed on the CITES appendices as a domestic animal.
- Because the ferret is domesticated, conservation concern attaches not to it but to its wild relatives, especially the Endangered black-footed ferret.

## Key facts: Ferret
- The ferret is a domesticated animal bred from the wild European polecat, not a wild species in its own right.
- It belongs to the weasel family (Mustelidae) and is an obligate carnivore that thrives on a meat-based diet.
- Ferrets are renowned for their playfulness, including the bouncy, sideways "weasel war dance".
- They have been used for centuries to hunt rabbits and rodents out of their burrows, a practice called ferreting.
- The domestic ferret should not be confused with the Endangered black-footed ferret of the North American prairies.
- Pet ferrets are legal in many places but restricted or banned in some jurisdictions, so always check local laws first.

## What kind of animal is a ferret?
The ferret is a domesticated mammal in the genus Mustela and the family Mustelidae, which also includes weasels, stoats, polecats, mink and otters. Its scientific name, Mustela furo, reflects its place among the true weasels. Like its relatives, the ferret has a long, tubular body, short legs, a flexible spine and a pointed face, an anatomy perfectly suited to following prey down narrow tunnels. Adults usually measure around 50 cm in head-and-body length with a tail of about 13 cm, and weigh between roughly 0.7 and 2 kg, with males noticeably larger than females. Coat colours range from the classic dark-masked "sable" through albino (white with pink eyes) to silver, cinnamon and chocolate. Genetic and historical evidence indicates the ferret was domesticated from the European polecat (Mustela putorius) around 2,500 years ago, most likely to control rabbits and rodents. This long shared history with people makes the ferret a true domestic animal, comparable to the cat or dog rather than a tamed wild creature.

## How do ferrets behave, and what do they eat?
Ferrets are intelligent, inquisitive and famously playful. They sleep deeply for 14 to 18 hours a day and are most active around dawn and dusk, a crepuscular rhythm inherited from their hunting ancestors. When awake and excited they perform the "weasel war dance": a frenzied series of sideways hops, bumps and backward shuffles that signals pure delight rather than aggression. They are social by nature and often kept in pairs or small groups, communicating through soft chuckles known as "dooking". As members of the weasel family, ferrets are obligate carnivores: their digestive systems are built to process meat, and they cannot extract nutrition efficiently from plant matter. A suitable diet is high in animal protein and fat and low in carbohydrate and fibre, supplied either as a specially formulated ferret food or an appropriate whole-prey or raw diet. Their fast metabolism and short gut mean they eat little and often. Curiosity and a talent for squeezing through gaps also make ferrets escape artists, so secure housing and supervised play are essential.

## What have ferrets been used for, and are they legal to keep?
For most of their history, ferrets earned their keep as working animals. The practice of "ferreting" sends a ferret into a rabbit warren to flush the occupants out into nets or towards waiting hunters, a tradition recorded since Roman times and still used in parts of Europe today. In the 19th and early 20th centuries ferrets were widely employed to protect grain stores and farms from rodents, including across the American West before modern pest control. Their slender build also led to occasional industrial use threading cables and wires through narrow conduits. Today most ferrets are kept simply as companions. Legality, however, varies considerably: ferrets are legal across most of the United Kingdom and many other countries and US states, but they are banned or tightly restricted in some places, including California, Hawaii and New York City, often over concerns about feral populations or rabies vaccination status. Anyone considering a ferret should confirm local regulations, licensing and vaccination requirements before bringing one home.

## Is the ferret the same as the black-footed ferret?
No, and the distinction matters for conservation. The domestic ferret (Mustela furo) is a tame, widely kept animal with no wild population to conserve and no IUCN Red List threat assessment. The black-footed ferret (Mustela nigripes) is an entirely separate species native to the grasslands and prairies of North America, where it preys almost exclusively on prairie dogs. Once thought extinct, the black-footed ferret was rediscovered in 1981 and remains one of the most endangered mammals on the continent, classified by the IUCN as Endangered and dependent on intensive captive breeding and reintroduction. The European polecat (Mustela putorius), the wild ancestor of the domestic ferret, is a third, distinct animal still found across much of Europe. Confusing these species can muddle public understanding of which animals actually need protection. When people picture a "ferret" as a pet, they mean Mustela furo; when conservationists discuss a ferret in peril, they almost always mean the black-footed ferret of the American plains.

## What WARN does
WARN does not run field conservation projects for the domestic ferret, because it is a domesticated companion animal rather than a wild or threatened species; this guide is part of WARN's free public education work. The wider threats that endanger the ferret's wild relatives, such as the habitat loss and prey decline behind the black-footed ferret's plight, are the very same pressures facing the wild animals WARN does help protect.

If you have learned something new here, a small gift helps keep WARN's wildlife education free and supports the wild animals whose homes are disappearing.

## Frequently asked questions: Ferret
### Is a ferret a rodent?
No. Despite their small size and long bodies, ferrets are not rodents. They are carnivores in the weasel family (Mustelidae), closely related to polecats, stoats, weasels and mink. Rodents such as rats and mice belong to a completely different order and are gnawing herbivores or omnivores, whereas ferrets are obligate meat-eaters that historically hunted rodents and rabbits.

### How long do pet ferrets live?
Domestic ferrets typically live for about seven to ten years, longer than many small pets. Lifespan depends on genetics, diet and veterinary care. As obligate carnivores they need a high-protein, meat-based diet, and they are prone to certain health problems as they age, so regular check-ups with a vet experienced in ferrets help them live a full and comfortable life.

### What is the difference between a ferret and a polecat?
The polecat is the wild animal; the ferret is its domesticated descendant. The European polecat (Mustela putorius) lives wild across much of Europe, while the domestic ferret (Mustela furo) was bred from it around 2,500 years ago for hunting and companionship. They can interbreed, and escaped ferrets sometimes mix with wild polecats, but the ferret is a tame, human-shaped animal.

### Are ferrets legal to keep as pets?
It depends on where you live. Ferrets are legal across most of the United Kingdom and in many other countries and US states, but they are banned or restricted in some places, including California, Hawaii and New York City. Restrictions often relate to fears of feral populations or rabies vaccination rules. Always check your local laws and any licensing requirements before getting one.

### What is the weasel war dance?
The "weasel war dance" is a burst of frenzied, joyful hopping that ferrets and their weasel relatives perform when excited or at play. It involves sideways leaps, arched backs, bumping into things and backward shuffles, often accompanied by soft clucking sounds called "dooking". Despite the warlike name it signals happiness and an invitation to play, not aggression or fear.

### Why is the black-footed ferret endangered but the pet ferret is not?
They are different species. The pet ferret (Mustela furo) is domesticated, kept worldwide and has no wild population at risk, so it is not assessed for conservation. The black-footed ferret (Mustela nigripes) is a wild North American species that nearly went extinct due to habitat loss and the decline of prairie dogs, its main prey. The IUCN lists it as Endangered, and it survives largely through captive breeding and reintroduction.
