White Ferret / Albino Ferrets

The emergence of white fur, like the white Ferret, in nature is often a rousing success or a lethal failure and rarely little in between.

The snowshoe hare — which shows off-white fur to hide in the snow during the winter and a browner coat in the off-seasons — has learned that even in the right environment, white isn’t always a good look. But the common ferret is unique in that white incidence of the species has actually been bred into members of the species intentionally and for purely aesthetic purposes.

And since the common ferret is a distinct subspecies of the European polecat with no wild counterparts, predators don’t factor into the survival of white members of the species. In fact, white ferrets can actually take two forms: fully albino ferrets and those that simply possess all or mostly white fur.

White Ferret Facts

• Dark-eyed whites are more likely to be deaf, while albino ferrets are often hard of hearing but rarely fully deaf.
• All ferret kits are born with fully white coats, although most of them begin to develop a set of darker colors and patterns at around three weeks old.
• The critically endangered black-footed ferret is the only other animal to wear the title of ferret, though they’re only distantly related by way of sharing the European polecat as an ancestor.
• Thanks to selective breeding, neither dark-eyed white ferrets nor albino ferrets are especially rare — and either can be found for around the same price as ferrets in other colors and patterns.

Scientific Name

Since they’re just regular ferrets with either an instance of albinism or a dark-eyed white coloration, white ferrets don’t have a distinct species name — but the scientific name of the common ferret actually tells us a lot.

The taxonomic identification for this species is Mustela putorius furo, and that technically makes ferrets a subspecies of their direct ancestor the European polecat (Mustela putorius).

As members of the genus Mustela, both European polecats and common ferrets are part of the weasel family (Mustelidae) and are related to the mink and stoat.

The white ferret’s taxonomy tells us a lot, but we can also learn quite a bit by translating Latin.

• Mustela: The full word — which refers to the genus that both the European polecat and the ferret belong to — translates directly as a weasel, which is itself derived from “mus”, or “mouse”.
• Putorius: The English word putrefaction is a particularly vivid way of referring to the decomposition process. It’s also derived from this Latin word, which assigns the smell of rotting flesh as a point of identification for these creatures.
• Furo: It’s likely that this is a reference to the Latin word “fur”, which translates to “thief” or “robber” It’s a name that fits given how deft and curious these creatures are. But this word could also be plausibly translated from Latin as cat.

Evolution and Origins

Ferrets are part of the Mustelidae family, which also encompasses species like polecats, stoats, and ermines. Domestic ferrets are thought to have originated from the European polecat and were domesticated roughly 2,500 years ago.

Ferrets are taxonomically classified as Mustela putorius furo, which designates them as a subspecies of their ancestor, the European polecat (Mustela putorius).

Furthermore, every existing ferret originates from the Stromer’s polecat (Mustela stromeri), a diminutive European species from the Middle Pleistocene era (roughly 790,000 to 130,000 years ago).

Appearance

Apart from their coats, these cute ferrets are indistinguishable from their darker and more colorful counterparts. The difference is merely one of pigmentation. There are some points of differentiation between the two distinct types of white ferret though. The easiest point of identification is the eyes.

Albinism causes ferrets to develop bright red eyes, while dark-eyed ferrets aptly enough have black eyes. Dark-eyed ferrets will sometimes have slight coloration or patterns in other colors or shades, and that can be another sure sign that you’re not dealing with an albino ferret.

While short-haired ferrets are the most common breeds, you can also find albino and dark-eyed white ferrets with long hair or even afghan fur.

Behavior

White ferrets are the same as ferrets in terms of behavior — energetic and mischievous creatures with slinky and agile bodies that allow them to sneak practically anywhere and climb onto any surface. Being white at least means that you can potentially find where they’re hiding more easily.

It is important to keep in mind that ferrets are wild animals and obligate carnivores who can be easily scared. This is something to be doubly cautious about when dealing with a white ferret.

Albino ferrets are often hard of hearing because of smaller components in their inner ear, and the lack of pigmentation in the lens of their eyes leaves them with terrible vision.

Dark-eyed white ferrets are also one of the variations more prone to deafness acquired by a condition known as Waardenburg Syndrome. You may need to adjust your behavior to avoid scaring white ferrets as a result of these sensory limitations.

Habitat

If ferrets were to live in the wild, they’d likely follow the instincts they inherited from the polecat and either dig burrows to hide in or abscond with burrows left behind by moles, rabbits, or snakes.

They still adore digging through anything, and many human companions of ferrets make sure to equip their habitats with plenty of different materials to burrow into.

Habitats should generally be 2′ x 2′ x 3′ and include a secure door. Ferrets are known for being escape artists, and white ferrets are no exception. When dealing with albinos, you should be especially aware of the lighting since they’re especially photosensitive.

Diet

The facts are that the ferret we know today never had to exist in anything resembling the wild, but they once served a purpose as more than just mischievous companions and itinerate thieves.

Five centuries before the beginning of the Common Era, ferrets were initially tamed to hunt rats, mice, and rabbits. That’s also where they got their high sense of energy.

Ferrets were voracious hunters with long and flexible bodies that allowed them to chase their prey into burrows and holes. They aren’t quite such capable hunters now, but that legacy makes a convincing argument for feeding raw meat like chicken and beef or even live meals to a ferret.

There are also a number of different dry food brands catered to the needs of ferrets as well as an extensive selection of treats.

Predators and Threats

While dogs left in the wild are sometimes known to revert to their native instincts and run in packs and colonies of domesticated cats can decimate a community’s bird population, the domestication of the ferret has left it utterly incapable of surviving in the wilderness. The ferret as it exists today never has to exist in the wild, and thousands of years of domestication have left it incapable of functioning in an ecosystem it’s thrown into.

While their fellow domesticated animals can breed and procreate after being released into the wild, the closest relative to the ferret to live in the wild is the European polecat. And unless they’re long-haired and left in the snow, their white fur is only going to make them an obvious target for predators.

In the average neighborhood where pet ferrets are kept, this could mean everything from birds of prey like hawks and eagles to wild scavengers like coyotes and foxes to house cats and pet dogs.

Reproduction and Life Cycle

While some convey the red eyes and white fur of albino ferrets with sickliness, these cute ferrets don’t actually have any distinct vulnerabilities to disease or negative health conditions. The average ferret is fully weaned after three to six weeks and will reach sexual maturity around the age of six months. The lifespan of a white ferret is the same as the lifespan of any other ferret — seven to ten years.

Ferret mating season falls anywhere from the spring to the summer, and a mother can give birth to as many as seven kits in a litter. Since ferrets are fully domesticated breeds with no actual predators, the population could quickly grow out of control if not for conscientious breeding habits from humans.

Population

While there’s no global estimate on the population size for either albino or dark-eyed white ferrets, the prices associated with these pets can tell us a decent amount about how rare they are in the overall ferret population. Both types of white albinos can sometimes be found for $50, making them among some of the more affordable choices.

In the wild, these sorts of traits would be rare — but we’ve been thousands of years meticulously breeding these traits through one generation after another. There are believed to be at least five million pet ferrets in the United States today, and neither the subspecies nor its white-coated members are going anywhere anytime soon. But the related black-footed ferret is another story.

With a population that hovers around 300, they’re the most endangered mammal in North America.
