Ferrets & Polecats

Polecats are medium-sized mustelids, with a heavier, bulkier build than the smaller weasels. Like most mustelids, polecats have short legs and elongated bodies and necks. Most polecats have shaggy fur that grows thicker in the winter but does not change color. They have long claws and are adept at digging burrows and hunting small animals including rodents, lizards, and frogs. Their muzzles are pointed, their ears are low-set and rounded, and their noses range in color from pink to black. All polecats have small, dark brown eyes and long whiskers on their muzzles, wrists, and “eyebrows”. Their pointed upper canine teeth often protrude from their closed mouths as “fangs”. Like other mustelids polecats can emit a foul odor from their anal glands when threatened. Polecats are less agile than the smaller weasels, looking somewhat ungainly when they move about with arched backs. Still, they have the same bounding gait and can also sit up on their hind legs to survey their surroundings.

Some say the purpose of a polecat’s dark facial mask is to reduce sun glare. Other sources believe it helps make their shiny, dark eyes less obvious to other animals; making them inconspicuous.

Common Misconceptions

Despite the name, polecats have no relation to cats. “Pole” probably comes from the old French word “poule”, meaning “hen” or “chicken”; likely in reference to the species’ fondness for poultry, while “cat” was most likely the closest animal people could compare it to due to limited knowledge of the species at the time.

Because of its resemblance to the striped polecat, skunks are incorrectly called polecats. Skunks are also frequently still mistaken for mustelids. They were once included as a subfamily of Mustelidae, but in the late 1990s skunks were given their own classification Mephitidae. (Research: Dragoo and Honeycutt 1997)

The black-footed ferret, also known as the American polecat, lives in prairies and preys exclusively on prairie dogs, and as such is extremely endangered. This polecat is not closely related to the domestic ferret but has a similar appearance due to its dark legs and mask. Its fur (primarily tan and cream except for the black legs, tail tip, and mask) is much shorter than the European and marble polecats and it has a thinner, slinkier, more weasel-like appearance with its long neck and larger ears. Black-footed ferrets have distinctive white “eye spots’ in the dark mask over their eyes.

Conservation Status: Endangered

(2) European Mink (Mustela lutreola)

The European mink, also known as the Russian mink and Eurasian mink, is a semiaquatic species native to Europe. It is genetically a polecat and actually has little in common with the American mink, which it’s often compared with. The two species are similar in colour, but the European mink is slightly smaller, has a less specialized skull, coarser fur and is not as adapted to the wet element as its namesake. If spotted in the field where these traits are difficult to see, the white markings on the upper lip can be counted on as a safe characteristic for identification. 

The European mink is closely related to the European- and steppe polecat, the ferret and the Siberian weasel, and breeding experiments back in the late 1970’s have resulted in a number of hybrids. The most famous is the khonorik, the offspring of an Euro-or steppe polecat and an European mink.

Size: 38-43 cm / 15-17 in (males), 36-41 cm / 14-16 in (females)
Weight: 544-816 g / 1.2-1.8 lb (males), 742 g / 1.6 lb (females)
Average Lifespan: 6 years
Range: Isolated areas of northern Spain and western France. Main range in small pockets of eastern Europe.
Conservation Status: Critically Endangered

(3) European Polecat (Mustela putorius)

The European polecat, also known as the common ferret, is a species native to western Eurasia and north Morocco. They typically have brown fur, with darker, sometimes black legs, tail, and underside, a dark mask across the eyes, and white around the nose and mouth. Their fur is shaggy, with dark guard hairs over a lighter undercoat, given them a grizzled appearance. Their tails taper to a point and are about one third the length of their body.

European polecats are so adept at hunting in burrows and tunnels that they have been domesticated to hunt rodents and rabbits. The domesticated European polecat is known as a ferret, and while ferrets were initially albino (white with pink eyes), pet ferrets are now available in a variety of colors, including typical wild polecat markings with a dark mask, legs and tail (referred to as “sable” coloration). Ferrets’ noses can be pink, speckled, dark brown, or black, while wild European polecats usually have black noses. The closely related steppe polecat is very similar in appearance to the European polecat, although its fur tends to be lighter, with fewer dark markings.

Size: 35.5-47.7 cm / 14-18 in (males), 27.9-40.6 cm / 11-16 in (females)
Weight: 997-1497 g / 2.2-3.3 lb (males, middle Europe), 635-816 g / 1.4-1.8 lb (females, middle Europe)
Average Lifespan: 5 years
Range: Widespread throughout most of Europe to western Russia.
Conservation Status: Least Concern

(4) Ferret (Mustela putorius furo)

Ferrets typically have brown, black, white, or mixed fur. They have an average length of 51 cm (20 in) including a 13 cm (5.1 in) tail, weigh about 1.5–4 pounds (0.7–2 kg), and have a natural lifespan of 7 to 10 years. Ferrets are sexually dimorphic predators with males being substantially larger than females.

Behavioral Misconceptions

People sometimes assume average house pet ferrets are aggressive like weasels, but ferrets’ characteristics are profoundly different from wild mustelids. Although “weasel” is a common nickname for the ferret, ferrets are not weasels. They have been domesticated for over two-thousand years, and unlike weasels or their European polecat cousin, ferrets have lost many of their natural instincts and cannot reproduce or survive in the wild. This applies mainly to those living in the United States and other areas where they are solely bred as house pets. In Europe and other parts of the world some ferrets are bred for hunting (known as ferreting), kept outside or fed live prey. These ferrets have a higher chance of surviving in the wild if they escape or are abandoned, and can breed with European polecats, resulting in ferret-polecat hybrids.

Unfortunately, average house pet ferrets are prone to the same negative misunderstandings and fearmongering as other mustelids in media, when in reality they’re no more aggressive or dangerous than your average dog or cat. For instance, reports have circulated claiming that infants have been bitten by a pet ferret while sleeping, but similar incidents have also been reported about dogs and cats; making these unfortunate events likely isolated cases, rather than general behavior. Due to these and several other misconceptions about the domesticated house pet ferret, they are banned as pets in the following areas across the world:

• North America: California, Hawaii, District of Columbia, and New York City.
• Australia: Queensland, Northern Territory.
• Europe: Portugal
• Africa: South Africa
• Oceania: New Zealand

Size: 46-61 cm / 18-24 in (males),  46 cm / 18 in (females)
Weight: 1.5-2.5 kg / 3-5 lb (males), 0.75-1.5 kg / 1.5-3 lb (females)
Average Lifespan: 7 to 10 years
Range: Domesticated
Conservation Status: Domesticated

(5) Steppe Polecat / Masked Polecat (Mustela eversmanii)

The steppe polecat, also known as the white polecat, masked polecat, or Siberian polecat, is a species native to Central and Eastern Europe and Central Asia. They are usually cream to maize-yellow in colour, along with dark brown limbs and a similar coloured tail tip. Their faces are mostly off-white in colour with a brown mask. At times the head can be completely white. 

Steppe polecats live in several burrows in its territory. These burrows are usually not dug by steppe polecat, but instead uses those of mammals it has hunted. Males have territories near female territories, and the sexes only socialize for mating from March till May. They hunt ground squirrels, rabbits, lizards, frogs, birds, insects and fruit; but they are renowned for their skill in hunting rodents. Steppe polecats play a major role in controlling rodent populations; which can be hazardous to both agriculture and human health. However, they are also trapped by locals in their region for their meat and fur.

Size: 32-56 cm / 13-22 in (males),  29-52 cm / 11-20 in (females)
Weight: 2,050 g / 4.5 lb (males), 1,350 g / 3 lb (females)
Average Lifespan: Not reported.
Range: Throughout central and eastern Europe.
Conservation Status: Least Concern


Although the following are called ‘polecats’, they are not closely related to the polecat species above.

(6) Marbled Polecat (Vormela peregusna) – Genus Vormela

The marbled polecat has an unusual and very striking appearance for a mustelid – with brightly-colored fur, a long bushy tail it will curve over its back to appear larger when threatened, and shaggy white fur on its ears. It has a dark brown to black underside, legs and facial mask; with white markings on its muzzle, forehead, and tail. Its back is covered in yellow-orange fur with irregular brown or black spots and markings.

Marbled polecats are solitary animals, and tend to become aggressive when meeting another. When threatened, it arches back its head and bares its teeth, while releasing shrills and short hisses. They tend to dwell in the burrows of large ground squirrels or similar rodents, but may also dig their own dens or live underground. Marbled polecats tend to avoid mountainous regions.

Their natural diet consists of rodents, small hares, birds, small reptiles, amphibians, fish, snails, insects and fruit.

Size: 29-35 cm / 11.4-13.7 in (males)
Weight: 320-715 g / 11-25 oz (males), 295-600 g / 10-21 oz (females)
Range: Southeast Europe to Russia and China.
Conservation Status: Vulnerable

(7) Saharan Striped Polecat (Ictonyx libycus) – Genus Ictonyx

(8) Striped Polecat / Zorilla (Ictonyx striatus) – Genus Ictonyx

Photo credit unknown.

The striped polecat, also known as the African polecat, zoril, zorille, zorilla, Cape polecat, and African skunk (despite not being a skunk), lives in diverse dry and arid climates from central to southern Africa in over 40 African countries. Despite their appearance and anal spray defense mechanism, they are not skunks. In fact, skunks tend to be incorrectly called polecats because of their similar appearance to the striped polecat. Unlike skunks, striped polecats have three white spots on the head, and four distinct stripes along the length of their bodies to the tips of their tail. 

One of the main differences between a striped polecat and a skunk, is skunks are omnivores, while the striped polecat is carnivorous. Striped polecats consume insects, lizards, snakes and centipedes, but its main diet consists of rodents.

The striped polecat is a solitary, aggressive and territorial animal – mainly associating with other members of its species for the purpose of mating. They are nocturnal animals, and spend most of their time on the ground and live in the burrows that they dig, but often sleep in hollow trees or rock crevices. When threatened, they spray a foul odor from their anal glands. It is believed that the striped polecat’s spray may be more potent than that of the skunk’s.

Size: 28-38 cm / 11-15 in (males)
Weight: 681-1460 g / 1.5-3 lb (males), 596-880 g / 1.3-2 lb (females)
Average Lifespan: Not reported.
Range: South Africa, to as far north as Central Africa.
