The ferret (Mustela putorius furo) is the domesticated form of the European polecat, a mammal belonging to the same genus as the weasel, Mustela of the family Mustelidae.[1] They 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.[2] Ferrets are sexually dimorphic predators with males being substantially larger than females.

Several other Mustelids also have the word ferret in their common names, including an endangered species, the black-footed ferret.

The history of the ferret's domestication is uncertain, like that of most other domestic animals, but it is likely that ferrets have been domesticated for at least 2,500 years. They are still used for hunting rabbits in some parts of the world, but increasingly, they are kept only as pets.

Being so closely related to polecats, ferrets easily hybridize with them, and this has occasionally resulted in feral colonies of polecat-ferret hybrids that have caused damage to native fauna, especially in New Zealand.[3] As a result, some parts of the world have imposed restrictions on the keeping of ferrets.

Etymology

The name "ferret" is derived from the Latin furittus, meaning "little thief", a likely reference to the common ferret penchant for secreting away small items.[4] The Greek word ictis occurs in a play written by Aristophanes, The Acharnians, in 425 BC. Whether this was a reference to ferrets, polecats, or the similar Egyptian mongoose is uncertain.[5]

Biology

Characteristics

Ferret profile

Ferrets have a typical Mustelid body-shape being long and slender. Their average length is about 50 cm including a 13-cm tail. Their pelage has various colorations including brown, black, white or mixed. They weigh between 0.7 kg to 2.0 kg and are sexually dimorphic as the males are substantially larger than females. The average gestation period is 42 days and females may have 2 or 3 litters each year. The litter size is usually between 3 to 7 kits which are weaned after 3 to 6 weeks and become independent at 3 months. They become sexually mature at approximately 6 months and the average life span is 7 to 10 years.[6][7]

Behavior

Ferrets spend 14–18 hours a day asleep and are most active around the hours of dawn and dusk, meaning they are crepuscular.[8] Unlike their polecat ancestors, which are solitary animals, most ferrets will live happily in social groups. A group of ferrets is commonly referred to as a "business".[9] They are territorial, like to burrow, and prefer to sleep in an enclosed area.[10]

Like many other mustelids, ferrets have scent glands near their anus, the secretions from which are used in scent marking. Ferrets can recognize individuals from these anal gland secretions, as well as the sex of unfamiliar individuals.[11] Ferrets may also use urine marking for sex and individual recognition.[12]

As with skunks, ferrets can release their anal gland secretions when startled or scared, but the smell is much less potent and dissipates rapidly. Most pet ferrets in the US are sold de-scented (anal glands removed).[13] In many other parts of the world, including the UK and other European countries, de-scenting is considered an unnecessary mutilation.

When excited, they may perform a behaviour commonly called the weasel war dance, characterized by a frenzied series of sideways hops, leaps and bumping into nearby objects. Despite its common name, this is not aggressive but is a joyful invitation to play. It is often accompanied by a soft clucking noise, commonly referred to as "dooking".[14] In contrast, when scared, ferrets will make a hissing noise; when upset, they will make a soft 'squeaking' noise.[15]

The UK accepts ferrets under the EU's PETS travel scheme. Ferrets must be microchipped, vaccinated against rabies, and documented. They must be treated for ticks and tapeworms 24 to 48 hours before entry. They must also arrive via an authorized route. Ferrets arriving from outside the EU may be subject to a six-month quarantine.[65]

United Kingdom

As of July 2004, dogs, cats, and ferrets can travel freely within the European Union under the Pet passport scheme. To cross a border within the EU, ferrets require at minimum an EU PETS passport and an identification microchip (though some countries will accept a tattoo instead). Vaccinations are required; most countries require a rabies vaccine, and some require a distemper vaccine and treatment for ticks and fleas 24 to 48 hours before entry. Ferrets occasionally need to be quarantined before entering the country. PETS travel information is available from any EU veterinarian or on government websites.

Ferrets brought from anywhere except the US require a Permit to Import from the Canadian Food Inspection Agency Animal Health Office. Ferrets from the US require only a vaccination certificate signed by a veterinarian. Ferrets under three months old are not subject to any import restrictions.[64]

Ferrets cannot be imported into Australia. A report drafted in August 2000 seems to be the only effort made to date to change the situation.[63]

Import restrictions

  • Australia – It is illegal to keep ferrets as pets in Queensland or the Northern Territory; in the ACT a licence is required.
  • Brazil – They are allowed only if they are given a microchip identification tag and sterilized.
  • New Zealand – It has been illegal to sell, distribute or breed ferrets in New Zealand since 2002 unless certain conditions are met.[48]
  • United States – Ferrets were once banned in many US states, but most of these laws were rescinded in the 1980s and '90s as they became popular pets.

Regulation of ferrets as pets

Gaston Phoebus' Book Of The Hunt was written in approximately 1389 to explain how to hunt different kinds of animals, including how to use ferrets to hunt rabbits. Illustrations show how multicolored ferrets that were fitted with muzzles were used to chase rabbits out of their warrens and into waiting nets.

"The Ferreter's Tapestry" is a 15th-century tapestry from Burgundy, France, now part of the Burrell Collection housed in the Glasgow Museum and Art Galleries. It shows a group of peasants hunting rabbits with nets and white ferrets. This image was reproduced in Renaissance Dress In Italy 1400–1500, by Jacqueline Herald, Bell & Hyman – ISBN 0-391-02362-4.

White ferrets were favored in the Middle Ages for the ease in seeing them in thick undergrowth. Leonardo da Vinci's painting Lady with an Ermine is likely mislabelled; the animal is probably a ferret, not a stoat, (for which "ermine" is an alternative name for the animal in its white winter coat). Similarly, the ermine portrait of Queen Elizabeth the First shows her with her pet ferret, which has been decorated with painted-on heraldic ermine spots.

Waardenburg-like coloring

There are four basic colors. The sable (including chocolate and dark brown), albino, dark eyed white (DEW), and the silver. All the other colors of a ferret are variations on one of these four categories.

Most ferrets are either albinos, with white fur and pink eyes, or display the typical dark masked sable coloration of their wild polecat ancestors. In recent years fancy breeders have produced a wide variety of colors and patterns. Color refers to the color of the ferret's guard hairs, undercoat, eyes, and nose; pattern refers to the concentration and distribution of color on the body, mask, and nose, as well as white markings on the head or feet when present. Some national organizations, such as the American Ferret Association, have attempted to classify these variations in their showing standards.[47]

Terminology and coloring

  • Ferrets have been used in many broad areas of research, such as the study of pathogenesis and treatment in a variety of human disease, these including studies into cardiovascular disease, nutrition, respiratory diseases such as SARS and human influenza, airway physiology,[40] cystic fibrosis and gastrointestinal disease.
  • Because they share many anatomical and physiological features with humans, ferrets are extensively used as experimental subjects in biomedical research, in fields such as virology, reproductive physiology, anatomy, endocrinology, and neuroscience.[41]
  • Trained ferrets have been successfully used for many years to assist in leading wires and cables in confined spaces in buildings and aircraft manufacture. A length of light line is attached to a harness around the ferret's chest, and the animal is coaxed to run through the confined space, pulling the lead string with it. The string is then used to pull the cables.[42]
  • In the UK, ferret racing is often a feature of rural fairs or festivals, with people placing small bets on ferrets that run set routes through pipes and wire mesh. Although financial bets are placed, the event is primarily for entertainment purposes as opposed to 'serious' betting sports such as horse or greyhound racing.[43][44]

Ferrets are an important experimental animal model for human influenza,[37][38] and have been used to study the 2009 H1N1 (swine flu) virus.[39] Smith, Andrews, Laidlaw (1933) inoculated ferrets intra-nasally with human naso-pharyngeal washes, which produced a form of influenza that spread to other cage mates. The human influenza virus (Influenza type A) was transmitted from an infected ferret to a junior investigator, from whom it was subsequently re-isolated.

Other uses of ferrets

In the United States, ferrets were relatively rare pets until the 1980s. A government study by the California State Bird and Mammal Conservation Program estimated that by 1996 about 800,000 domestic ferrets were being kept as pets in the United States.[36]

The practice is illegal in several countries where it is feared that ferrets could unbalance the ecology. In 2009 in Finland, where ferreting was previously unknown, the city of Helsinki began to use ferrets to restrict the city's rabbit population to a manageable level. Ferreting was chosen because in populated areas it is considered to be safer and less ecologically damaging than shooting the rabbits.

For millennia, the main use of ferrets was for hunting, or ferreting. With their long, lean build, and inquisitive nature, ferrets are very well equipped for getting down holes and chasing rodents, rabbits and moles out of their burrows. Caesar Augustus sent ferrets or mongooses (named "viverrae" by Plinius) to the Balearic Islands to control the rabbit plagues in 6 BC.[32][33] In England, in 1390, a law was enacted restricting the use of ferrets for hunting to the relatively wealthy:

Ferreting

Colonies of feral ferrets have established themselves in areas where there is no competition from similarly sized predators, such as in the Shetland Islands and in remote regions in New Zealand. Where ferrets coexist with polecats, hybridization is common. It has been claimed that New Zealand has the world's largest feral population of ferret-polecat hybrids.[30] In 1877, farmers in New Zealand demanded that ferrets be introduced into the country to control the rabbit population, which was also introduced by humans. Five ferrets were imported in 1879, and in 1882–1883, 32 shipments of ferrets were made from London, totaling 1,217 animals. Only 678 landed, and 198 were sent from Melbourne, Australia. On the voyage, the ferrets were mated with the European polecat, creating a number of hybrids that were capable of surviving in the wild. In 1884 and 1886, close to 4,000 ferrets and ferret hybrids, 3,099 weasels and 137 stoats were turned loose.[31] Concern was raised that these animals would eventually prey on indigenous wildlife once rabbit populations dropped, and this is exactly what happened to New Zealand's bird species which previously had had no mammalian predators.

Ferrets were probably used by the Romans for hunting.[28][29]

In common with most domestic animals, the original reason for ferrets being domesticated by human beings is uncertain, but it may have involved hunting. According to phylogenetic studies, the ferret was domesticated from the European polecat (Mustela putorius), and likely descends from a North African lineage of the species.[25] Analysis of mitochondrial DNA suggests that ferrets were domesticated around 2,500 years ago, although what appear to be ferret remains have been dated to 1500 BC.[26] It has been claimed that the ancient Egyptians were the first to domesticate ferrets, but as no mummified remains of a ferret have yet been found, or any hieroglyph of a ferret, and no polecat now occurs wild in the area, that idea seems unlikely.[27]

History of domestication

Ferrets are known to suffer from several distinct health problems. Among the most common are cancers affecting the adrenal glands, pancreas, and lymphatic system. Viral diseases include canine distemper and influenza. Health problems can occur in unspayed females when not being used for breeding.[24] Certain health problems have also been linked to ferrets being neutered before reaching sexual maturity. Certain colors of ferret may also carry a genetic defect known as Waardenburg syndrome. Similar to domestic cats, ferrets can also suffer from hairballs and dental problems.

  • Twelve small teeth (only a couple of millimeters) located between the canines in the front of the mouth. These are known as the incisors and are used for grooming.
  • Four canines used for killing prey.
  • Twelve premolar teeth that the ferret uses to chew food—located at the sides of the mouth, directly behind the canines. The ferret uses these teeth to cut through flesh, using them in a scissors action to cut the meat into digestible chunks.
  • Six molars (two on top and four on the bottom) at the far back of the mouth are used to crush food.

Ferrets have four types of teeth (the number includes maxillary (upper) and mandibular (lower) teeth):

Ferret dentition

Dentition

[23] Before much was known about ferret physiology, many breeders and pet stores recommended food like fruit in the ferret diet, but it is now known that such foods are inappropriate, and may in fact have negative ramifications on ferret health. Ferrets imprint on their food at around six months old. This can make introducing new foods to an older ferret a challenge, and even simply changing brands of kibble may meet with resistance from a ferret that has never eaten the food as a kit. It is therefore advisable to expose young ferrets to as many different types and flavors of appropriate food as possible.[22] and the animal is largely unable to digest plant matter.cecum Ferret digestive tracts lack a [21][20]) to their ferrets to more closely mimic their natural diet.rabbits and mice though some ferret owners feed pre-killed or live prey (such as [19] provide the most nutritional value and are the most convenient,[18], although specialized ferret food is increasingly available and preferable)cat food Ferrets have short digestive systems and quick metabolism, so they need to eat frequently.
