Rat Coat Colours and Patterns

By Small Furries - May 08, 2019


If you've read my complete guide for new rat owners you'll know that all wild rats are either 'black' or 'brown', all domesticated rats have been bred from brown rats, all fancy rats are domesticated rats and the only difference between the two types of Larger Fancy rats are where their ears sit on their head!

Top Eared rats are also know as standard rats and their ears are positioned on top of their heads, where as Dumbo rats are bred specifically to get their ears on the side of their heads to make them look more cute for humans.

Manx Rats are born with no tail and Dwarf Rats are amazingly only 1/3 of the size of a standard rat!

The standard coat type for fancy rats is a straight, short smooth coat but rats can have curly hair too!

Rex rats have curly hair caused by a genetic mutation ( which can occur in a selection of other animals ) and makes them look like little sheep!

Rat breeders then selectively bred them to create the perfect rex rat but some have such curly hair, it starts to fall out! 

These rats also have curly whiskers and are called Double Rex Rats. They can also be known as Patchwork because of the missing patches of fur.

Some people mistake a balding double rex rat for a hairless or naked rat due to their lack of fur but they are actually different line of genetics!

Hairless can range from being completely naked with no eyebrows or whiskers to having  a thin layer of fuzzy soft fur, usually occurring around the rear and head.


Here are some of the most popular Coat Patterns:

Self - One solid colour all over

Agouti - Wild colour of rats with brown, black and grey hairs

Berkshire - Solid colour with white stomach, feet and tip of the tail

Blaze - A striking white mark between the eyes and nose

Capped - A pure white rat with a solid colour on the head

Hooded - A pure white rat with a solid colour on the head and a strip of solid colour down the spine

Variegated - A pure white rat with a solid colour on the head and flecks or patches of colour down the spine

Irish - Solid colour with white feet and a small patch on the stomach or chest

Masked - A pure white rat with a line of solid colour over the eyes

Roan/Husky - Born with a white stomach, a solid colour on their back and a white blaze on their head, the colour usually fades out over time

Dalmatian - A pure white rat with a large marking on the head and spotted markings on the body

Silvermane - A mixture of their natural colour and silver hairs with extra soft fur

Champagne - Warm beige with red eyes

Blue - Different varieties which range from a powder blue to a deep blue grey 

Siamese - A solid beige colour with brown patches on the nose and the top of the tail

Pink Eyed White/ Albino - A white rat with red eyes and no pigmentation on the skin

I've left this to the end because i don't want to make it too confusing!

Now you know a few of the coat colours and patterns, it also depends on the Base coat colour! Don't worry there is only two - Agouti ( Wild Rats ) and Black, and each coat colour changes depending on the base coat colour.

For example, if you were to put the coat colour Blue with an agouti base coat, the rat would have silver/blue/grey coat, the tips of the fur would be a beige colour and the belly would be slightly paler. But if you put Blue on a Black base coat colour, the rat would have one solid blue coat!
