Why Do Ferrets Smell? [All Reasons Explained!]

Ferrets are domesticated animals with uncertainty in when this process started. They have been undergoing domestication for the last 2500 years.

Reasons Ferrets Smell

Previously used for various hunting purposes, ferrets are now mostly kept as pets. However, they can cause your house to stink up faster than a clogged toilet. It is not their fault that it happens, but it is a mechanism they are gifted with!

Reasons For Ferret Odor

There are various reasons why ferrets have a natural stink. Just like skunks and weasels, they belong to the family Mustelidae. Animals belonging to this family have a natural bad scent. However, other reasons can cause a pungent smell in ferrets.

The Stench From Anal Glands

Ferrets occasionally produce a stench from their anal glands. Ferret experts refer to this as a ‘poof.’ This is generally rare and only happens when they are excited or scared.

However, this is a strong and unbelievably pungent smell that is a natural process of their bodies.

Adrenal Disease, Causing Smell

Ferrets with an illness, mainly adrenal disease, can also reek badly. The adrenal disease is responsible for making neutered ferrets act un-neutered. Their body starts to make excessive hormones due to tumors in the adrenal gland.

It is usually the sex hormone that is over-produced in their body. The immediate stimulation of excess hormone causes a pungent smell to occur from the ferret. The excess production of the sex hormone makes them act as if they haven’t been neutered, emitting extreme body odor.

Late Neutering

A ferret that has not been neutered immediately at birth or a little after that also produces odor. If ferrets are left un-neutered for long, and there is a delay in removing their sex organs, they start making a pungent smell.

This smell is similar to horse manure, and it is mainly due to ignoring the neutering process for too long.

Ferrets In ‘Season Of Stinking.’

This process occurs for whole ferrets who have not been subjected to neutering. When ferrets come into ‘season,’ mostly males, they produce a specific unpleasant smell.

This is their process of sexually attracting their mates, much like their ancestors. The males use this mechanism of stinking as a way to urge the females for sexual activity.

Why Do Ferrets Smell

However, this is unapplicable for ferrets that don’t have their sex organs removed, as they don’t have mating urges.

Excessive Bathing Of Ferrets

Ferrets are probably the only animals that reverse the psychology of the bathing process. They stink up more if they bathe more! There are general reasons why it is recommended only to bathe them once or twice a year.

Ferrets are oily animals with a lot of oil accumulating all over their body. This is a natural mechanism of their body, and that’s just how they are. If you bathe them, you are essentially removing the layer of oils from its body.

Hence, this stimulates them to produce more oil to lather their body. The more oil they produce, the smellier they become as the stench mainly comes from their oily body.

Smelly Ear Infections

Ferrets commonly acquire yeast or bacterial ear infections associated with having ear mites. These in themselves make them smell bad. However, it also makes their skin itchy and urges them to scratch it regularly.

This dries up their skin quickly and again impulses their body to produce excess oil. The excess oil also causes their bodies to smell. This is indicated with orange/brown deposits on their skins and can be caused due to water going in the ear.

However, with proper attention from a vet and rightly prescribed medication, they overcome this issue.

Poor Quality Diet

Ferrets that are not provided with the best diet usually tend to smell worse. They start to emit unusual, poor smells. Usually, food that contains fish tends to make their odor worse, according to experts.

The Ideal Ferret Diet Includes:

  • 30% crude protein of high digestibility.
  • 15-20% of fat, which is the most concentrated form of energy they receive.
  • Less than 4% fiber, ideally very little.

A diet fulfilling all their supplementary needs makes their body processes normal. This also makes their droppings smell bearable.

Unclean Environment

Ferrets that live in an environment that isn’t cleaned properly are usually the leading cause of smell complaints. It is vital to wash and sanitize their surroundings biweekly.

Their beddings, toys, enclosure, and litter boxes should be cleaned thoroughly and regularly. The oil on their fur rubs off on every surface they touch. Hence, it is important to clean their surroundings to control the stench. If proper care is not taken in this matter, you will have a ferret-like smell around your house.

Ample Time Outside The Cage

Ferrets are naturally curious animals that love exploring. It is crucial to allow them proper time out of their cages or enclosure. This is solely to feed their hunger of roaming about and playing.

Cooping them up in their cages for long periods can also accumulate unpleasant smells in their enclosure. It is important to let them and their skin breathe.

Proper Bedding Material

There are certain types of materials that catch onto the smells faster than others. Be aware of using a material that will soak up most of the oil from the ferret’s fur. This will only add up to the odor.

If one uses cloth blankets, hammocks, etc., the dirt and oil will come off. The ferret would smell fine, but the bedding becomes stinky. Unless you wash up the laundry regularly, this will also contribute to the issue at hand.


Even though ferrets have a naturally strong and musky scent to them, most owners get used to it. In unnatural conditions, if proper care is not taken regarding the cause, the ferrets are inclined to smell bad.

However, if authentic measures are taken regarding their medical and physical cleanliness, no issue is big enough.
