{{Short description|Domestic species of mammal}} {{About|the domesticated ferret|the endangered North American species|black-footed ferret|other uses}} {{Pp-semi-indef}} {{Speciesbox |name=Ferret |image=Ferret_2008.png |image_caption=A pet ferret |status = DOM |parent=Putorius |genus=Mustela |species=furo |authority=[[Linnaeus]], [[10th edition of Systema Naturae|1758]] |synonyms=''Mustela putorius furo'' <small>Linnaeus, 1758</small> }} The '''ferret''' ('''''Mustela furo''''') is a small, [[domesticated]] species belonging to the family [[Mustelidae]]. The ferret is most likely a domesticated form of the wild [[European polecat]] (''Mustela putorius''), as evidenced by the ferret's ability to interbreed with European polecats and produce [[Hybrid (biology)|hybrid]] offspring. Physically, ferrets resemble other mustelids because of their long, slender bodies. Including their [[tail]], the average length of a ferret is about {{cvt|50|cm}}; they weigh between {{cvt|0.7|and|2.0|kg}}; and their fur can be black, brown, white, or a mixture of those colours. The species is [[sexually dimorphic]], with males being considerably larger than females. Ferrets may have been domesticated since [[ancient times]], but there is widespread disagreement because of the sparseness of written accounts and the inconsistency of those which survive. Contemporary scholarship agrees that ferrets were bred for sport, hunting [[rabbit]]s in a practice known as [[rabbiting]]. In [[North America]], the ferret has become an increasingly prominent choice of household [[pet]], with over five million in the [[United States]] alone. The legality of ferret ownership varies by location. In [[New Zealand]] and some other countries, restrictions apply due to the damage done to native fauna by [[feral]] colonies of [[polecat–ferret hybrid]]s. The ferret has also served as a fruitful research animal, contributing to research in [[neuroscience]] and [[infectious]] disease, especially [[influenza]]. The domestic ferret is often confused with the [[black-footed ferret]] (''Mustela nigripes''), a species native to North America.<ref>{{Cite book|last1=Fox|first1=James G.|url=https://www.worldcat.org/oclc/863695703|title=Biology and Diseases of the Ferret|last2=Marini|first2=Robert P.|date=2014|publisher=John Wiley & Sons|isbn=978-1-118-78273-6|edition=3rd|location=Ames, Iowa|pages=5|oclc=863695703|access-date=2021-12-31|archive-date=2022-01-05|archive-url=https://web.archive.org/web/20220105232948/https://www.worldcat.org/title/biology-and-diseases-of-the-ferret/oclc/863695703|url-status=live}}</ref> ==Etymology== The name "ferret" is derived from the Latin {{Lang|la|furittus}}, meaning "little thief", a likely reference to the common ferret penchant for secreting away small items.<ref>[http://www.merriam-webster.com/dictionary/ferret ferret] {{Webarchive|url=https://web.archive.org/web/20090424030339/http://www.merriam-webster.com/dictionary/ferret |date=2009-04-24 }}.

These are used for grooming. * Four [[Canine tooth|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 [[molar (tooth)|molars]] (two on top and four on the bottom) at the far back of the mouth are used to crush food. ===Health=== [[Image:Jake 0314.jpg|thumb|Male ferret]] Ferrets are known to suffer from several distinct health problems. Among the most common are cancers affecting the [[adrenal glands]], [[pancreas]] and [[Lymphoma in ferrets|lymphatic system]]. Adrenal disease, a growth of the [[adrenal glands]] that can be either [[hyperplasia]] or cancer, is most often diagnosed by signs like unusual hair loss, increased aggression, and difficulty urinating or defecating. Treatment options include surgery to excise the affected glands, [[melatonin]] or deslorelin implants, and hormone therapy. The causes of adrenal disease speculated to include unnatural light cycles, diets based around processed ferret foods, and prepubescent neutering. It has also been suggested that there may be a hereditary component to adrenal disease.<ref>{{cite web |last=Johnson-Delaney |first=Cathy A |title=Proceedings of the Association of Exotic Mammal Veterinarians |publisher=AEMV |year=2006 |url=http://www.aemv.org/Documents/2006_AEMV_proceedings_10.pdf |access-date=2007-03-03 |url-status=dead |archive-url=https://web.archive.org/web/20070629140225/http://www.aemv.org/Documents/2006_AEMV_proceedings_10.pdf |archive-date=2007-06-29}}</ref> [[Insulinoma]], a type of cancer of the [[islet cell]]s of the pancreas, is the most common form of cancer in ferrets.

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.<ref>{{cite web |url=http://www.ferret.org/events/colors/colorchart.html |title=American Ferret Association: Ferret Color and Pattern Standards |publisher=Ferret.org |access-date=2008-11-30 |archive-date=2008-12-09 |archive-url=https://web.archive.org/web/20081209073612/http://www.ferret.org/events/colors/colorchart.html |url-status=live }}</ref> There are four basic colors. The sable (including chocolate and dark brown), albino, dark-eyed white (DEW, also known as black-eyed white or BEW) and silver. All the other colors of a ferret are variations on one of these four categories. ===Waardenburg-like coloring=== [[Image:Coco 4056.JPG|right|thumb|White or albino ferret]] Ferrets with a white stripe on their face or a fully white head, primarily blazes, badgers and pandas, almost certainly carry a congenital defect which shares some similarities to [[Waardenburg syndrome]]. This causes, among other things, a cranial deformation in the womb which broadens the skull, white face markings, and also partial or total deafness. It is estimated as many as 75 percent of ferrets with these Waardenburg-like colorings are deaf. 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 I]] shows her with her pet ferret, which has been decorated with painted-on [[Heraldry|heraldic]] ermine spots. ''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.

A report drafted in August 2000 seems to be the only effort made to date to change the situation.<ref>{{cite web|title=Importation of Ferrets into Australia, Import Risk Analysis – Draft Report|publisher=Australian Quarantine and Inspection Service (AQIS)|date=August 2000|url=http://www.daff.gov.au/corporate_docs/publications/pdf/market_access/biosecurity/animal/2000/00-036a.pdf |access-date=2006-09-12 |archive-url=https://web.archive.org/web/20060910063747/http://www.daff.gov.au/corporate_docs/publications/pdf/market_access/biosecurity/animal/2000/00-036a.pdf |archive-date=2006-09-10}}</ref> * '''Canada''' – 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.<ref>{{cite web |title=Importation of Foxes, Skunks, Raccoons and Ferrets |work=Pet Imports |publisher=Canadian Food Inspection Agency |date=2006-03-20 |url=http://www.inspection.gc.ca/english/anima/heasan/import/foxrene.shtml |access-date=2006-09-12 |url-status=dead |archive-url=https://web.archive.org/web/20090328022309/http://www.inspection.gc.ca/english/anima/heasan/import/foxrene.shtml |archive-date=2009-03-28}}</ref> * '''European Union''' – {{as of|2004|July}}, 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 [[Canine distemper|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. * '''New Zealand''' – New Zealand has banned the import of ferrets into the country.<ref>{{Cite web|url=https://www.customs.govt.nz/personal/move-to-nz-permanently/import-pets-and-animals/|title=Import pets and animals|website=Customs.govt.nz|access-date=15 February 2022}}</ref> * '''United Kingdom''' – 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 [[tick]]s 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.<ref>{{cite web |title=PETS: How to bring your ferret into or back into the UK under the Pet Travel Scheme (PETS) |work=Animal health & welfare |publisher=Department of Environment Food and Rural Affairs (defra) Crown copyright 2006 |url=http://www.defra.gov.uk/animalh/quarantine/pets/ferretpets.htm |access-date=2006-09-12 |url-status=dead |archive-url=https://web.archive.org/web/20060901095759/http://www.defra.gov.uk/animalh/quarantine/pets/ferretpets.htm |archive-date=2006-09-01}}</ref> ==See also== * [[Ferret-legging]] ==References== {{Reflist|refs= <!--ref name=Lewington>{{cite book |first=John H. |last=Lewington |title=Ferret Husbandry, Medicine and Surgery |edition=2nd |publisher=Elsevier |year=2007 |isbn=978-0-7020-2827-4|page=6}}</ref--> <ref name=jurek1998>Jurek, R.
