Coat Types in Rats

This page will explain the different coat types in rats. A Coat type is a gene that effects the texture of the coat. It has nothing to do with color.

Standard Hair

Standard Hair

This is the wild coat type. No frills just straight hair.

 

Rex

Rex

Curly Hair, curly whiskers. Males curl better than females. Additionally Agouti curls better than all other colors.

This rat is a baby Rex the whiskers are longer at this age.

 

Adult Rex whiskers. Adults Rex differently than babies. the coat will still be curly. 

 

 

Velveteen

Velveteen

Not to be confused with Rex. Velveteens are often mistaken for Rex but its actually simple to tell them apart. Velveteen have a wave to the whiskers not a curl, and the fur is thick and when you blow on it it you cannot see the skin. Rex are curly and you can easily blow on them to see the skin. Males curl better than females.

 

Hairless hr/hr

Hairless hr/hr

Hairless come in several varieties.

One is hr/hr which is mostly hairless with a little short curly hair on the nose, feet and small amount on the lower legs and short curly whiskers. You see them more times than any other.

Another is fz/fz which is the fuzzy variety. Fuzzy body and short curly whiskers.

And nu/nu. Nude. Totally bald and no whiskers. They look like a rubber chicken.

Currently looking through my old files for my old pictures on this one.

 

Harley

Harley

The long haired rat. 

 

Satin

Satin

This is real Satin. The AFRMA Satin. Its got a longer coat with long straight whiskers that go backwards toward the face. There is another gene people are calling Satin that you see these days, but its coat is not as nice as this one. these stay long the new ones get short hair as they age. They are 2 different genes. To each his own pick the one you like best.

Silvermane

Silvermane

Silvermane is often mistaken for a color. But is now thought of as a coat type. it adds silver hairs that color change in a patch pattern as the rat molts. Very pretty. The hair is translucent and shines. It is very, very soft. It can be on any color of rat.

 

 

Angora

Angora

Angora is genetically Harley, so its long coated, with a recessive curl modifier. Also super soft.

 

Note

Note on coat types, all of these genes can be mixed together on the same rat in different combinations. I am not going to post pictures of all the possibilities.

The only exception is the 3 types of Hairless. They are either one or the other visibly, but can carry the others. Hairless can be Rex or Double Rex though which looks like a Hairless but breeds like a normal Rex or Double Rex. and is genetically both. 

Also I am missing the bald double Rex which looks like a hairy Hairless except that they have longer normal Rex whiskers. Not the shirt hairless whiskers. I have never seen this in real life but they are common. My Rex do not bad as doubles so I do not have a picture of that. Mine get extra thick hair as doubles.
