Types of Cat Fur

Cat fur and hair are the same thing…

“Hair” is usually used to describe individual hairs, while fur refers to a cat’s entire coat, but both words are interchanged frequently.

Cat hair is made of the protein keratin… just like human hair, nails, and horse hooves.

Guard Hairs

Guard hairs are the longer and stiffer type of fur, found over or mixed with the awn hairs as part of a cat’s topcoat.

They determine the main color of the cat and help keep a cat dry because they shed water.

Awn Hairs

Awn hairs are also part of the topcoat and are most of what you see when looking at a cat’s fur.

They’re finer than guard hairs but coarser than the undercoat and usually not as long as guard hairs.

Awn fur help protect a cat from cold, water, sun, dirt, and radiation. Hairless cats don’t have this protection.

When a cat has a triple coat, the awn hairs are considered the second layer, with guard hairs as the topcoat and downy fur as the undercoat.

There’s some disagreement about whether the awn hairs are actually a separate coat.

If you have a purebred cat, you can check the breed standards for info about her coat… and anything else you want to know.

TICA and CFA are the main registries in North America and have the breed standards.

Most mixed breed cats have a double coat with the guard and awn hairs as one main overcoat.

The undercoat is the downy, soft, fluffy hair that helps keep a cat warm.

It must be carefully brushed and detangled frequently to prevent painful mats, especially tightly curled or long hair.

This undercoat is there as insulation and to help regulate body temperature… keeping a cat warm in cold weather.

It also gives added protection from predators, scratches, bumps, and punctures.

Some breeds are called “hairless” but have very thin fine down called “vellus”, similar to baby hair.

For example, Sphynx cats can range from almost completely bald to having a noticeable coat of vellus.

Vibrissae (Whiskers)

whiskers, tabby cat

Whiskers (“vibrissae”) are long, tough, tactile hairs on a cat’s face and body.

Their purpose is to help cats navigate their world, especially in darkness.

They’re very sensitive and can detect objects, people, and animals, including prey.

Whiskers on a cat’s face move according to how relaxed, alert or alarmed he is, helping people and other cats know their mood.

They can occasionally shed but not all at once and should NEVER be cut.

Breeds With Various Coats

Most breeds have double coats, but not all… and the hair being long or short doesn’t have anything to do with it.

Some longhaired breeds have a single coat… some double coated cats have short hair.

Mixed breeds should be checked individually to accurately determine the type of coat.

To find out if your cat has a double or single coat, feel the fur down to the skin.

A single coat will have only guard or awn hair and a double coat will have those plus a thicker, dense, downy layer underneath.

Hairless cats like Sphynx are indoor-only cats because they can’t regulate their body temperature well enough for hot and cold environments.

They don’t need normal brushing but do require extra grooming care, including baths, to keep their skin healthy.

Single Coat

Cats with single coats have the outer guard/awn hair… no layer of soft downy undercoat.

A single coat sheds less and requires less brushing, although it’s still best to brush once once a week and check their skin.

They rarely need baths but do need sufficiently warm temperatures since they don’t have the extra insulating layer.

Double Coat

Most cats have double coats… an undercoat topped by a mixture of awn and guard hairs.

Double coated cats should be brushed or combed at least 2-3 times a week… longhaired coats daily.

Pay attention to carefully removing small knots and tangles to prevent mats.

Double coats shed more than single coats simply because there’s a lot more fur and routine brushing cuts down the amount of fur left around the house.

Triple Coat

The Siberian (a.k.a., Siberian Forest Cat) has a thick, long, amazing triple coat, with all three types of fur.

It has long guard hairs on the outside, awn hairs underneath, and a shorter, downy undercoat beneath both for extra warmth.

The Siberian cat, in its natural habitat, needs this type of fur coat to survive the harsh winters of Siberia, Russia.

Surprisingly, this coat doesn’t easily get matted… but it does shed a lot, especially when seasons change from cold to hot.

Be sure you and others in your home are tolerant of cat fur on furniture and elsewhere!

Daily brushing will reduce shedding and hairballs, while being a relaxing activity for you both.

Crimped, wired, or curly cat fur is a genetic mutation, commonly called the “rex mutation”.

There are various mutations of this fur, which are complex and produce different hair colors, lengths, and types of curls.

All curly coated cats have a fine undercoat and no overcoat.

Their coat can’t absorb skin oils like other coats, leaving it greasy or waxy and the cat’s normal grooming habits can’t eliminate it.

When this happens, a bath is important, usually once a month.

Use mild shampoo made specifically for cats to preserve the delicate pH balance of their skin.

If your cat isn’t used to baths, you can use gentle, positive training methods to help him accept them.

Selkirk Rex & LaPerm

Selkirk Rex and LaPerm are cats with a dense and very curly type of fur.

While they’re low maintenance, these coats must be detangled to prevent painful mats, bald spots, itchiness, and allergies.

They need to be gently combed and brushed about twice a week, especially in the neck, legs, paws, and stomach area.

Use a slicker brush or grooming mitt to gently brush in the direction the hair grows.

Cornish & Devon Rex

Cornish and Devon Rex cats have looser curls that don’t mat as often, so they don’t need as much attention… but can still need baths.

Overgrooming by either you or the cat can cause bald spots on any rex, because the hair follicles are fragile.

You should still gently brush them occasionally and check their skin while petting for any signs of overgrooming.

Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
