Genotypes

Genotypes are a string of letters indicating the traits your character expresses and carries. This directly corresponds with their phenotype.

Genotypes are ordered the same as they're listed on this page. Traits at the top of the page will be on the left side of a genotype; traits at the bottom will be on the right side.

You must always include fur length, eumelanin, agouti, underlying tabby patterns (mackerel, spotted and ticked), and any other gene that your character carries or expresses.

If you need a visual guide to determining your cat's phenotype, head over to our Design Guide page.

Coats

Fur Length

Short fur (LL)

Short-haired cats don’t have any long tufts of fur on their bodies.


Short fur, carries long (Ll)

Same as short fur, except they carry the long hair gene.


Long fur (ll)

Your cat has long fur. Length can somewhat vary.



Glitter

Normal coat, carries glittered coat (Glgl)

Your cat has a normal coat, but carries glittering fur.


Glittered coat (glgl)

Your cat has glittering fur, like some Bengals and Egyptian Maus. Their fur refracts light, due to air pockets in the core of each hair shaft. This gives them a glittering appearance. The color is generally a lighter, brighter color of their coat color. For example, black tabbies have golden glitter, charcoals have silver glitter, and silver or pointed cats have crystal-white glitter.



Satin-Rexing

Normal coat, carries satin-rexed coat (Sasa)

Your cat has a normal coat, but carries satin-rexing. Their fur will be a bit shinier and softer than usual.


Satin-rexed coat (sasa)

Your cat has curly fur with a satin shimmer, similar to Tennessee Rex fur. Their fur is more tightly curled the shorter it gets, loosening up into soft curls or waves where it gets longer. All hairs reflect light, due to a coating on the hair shaft that is similar to oyster shell. This gives them a satin sheen which is most noticeable on lighter-colored or red cats. They also will have curled whiskers.



Cornish Rex

Normal coat, carries Cornish Rex coat (Rr)

Your cat has a normal coat, but carries a wavy coat similar to Cornish Rex fur.


Cornish Rex coat (rr)

Your cat has wavy fur that’s similar to Cornish Rex fur. Cats have three layers to their coat -- the guard, awn, and down layers. This fur mutation causes a lack of guard hairs, leaving only the awn and down layers which are very short, soft and fine. The hairs form a uniform wave pattern across the coat. Their whiskers are also often short and either crimped or curled.



Rex and Hairless

Normal coat, carries Devon Rex coat (Rere)

Your cat has a normal coat, but carries wavy-curly fur similar to Devon Rex fur.


Normal coat, carries hairless (Rehr)

Your cat has a normal coat, but carries the hairless gene.


Selkirk Rex coat (SReRe)

Your cat has curly fur similar to Selkirk Rex fur. They have a full coat with all three layers of hair (guard, awn, and down) intact. All hairs have a light, loose curl, and form ringlets across the coat. Carries non-Selkirk Rex gene.


Selkirk Rex coat (SReSRe)

Your cat has curly fur similar to Selkirk Rex fur. They have a full coat with all three layers of hair (guard, awn, and down) intact. All hairs have a light, loose curl, and form ringlets across the coat. As the homozygous variant, these cats will have more dense, tight curls than cats that are heterozygous for the gene.

Selkirk Rex coat (SRere)

Your cat has curly fur similar to Selkirk Rex fur. They have a full coat with all three layers of hair (guard, awn, and down) intact. All hairs have a light, loose curl, and form ringlets across the coat. Carries Devon Rex.

Your cat has curly fur similar to Selkirk Rex fur. They have a full coat with all three layers of hair (guard, awn, and down) intact. All hairs have a light, loose curl, and form ringlets across the coat. Carries hairless.

Devon Rex coat (rere)

Your cat has wavy-curly fur similar to Devon Rex fur. This fur mutation causes the guard hairs (outermost layer) of a cat's coat to be extremely short; their fur is wavy with a slight curl. Their whiskers are also often short and either crimped or curled.

Fur-pointed (hrre)

Your cat is fur-pointed. They have soft, rippled, dense fur on their face, ears, legs and tail, and sparse fur across the rest of the body with a nearly-hairless neck, chest and belly.


Hairless (hrhr)

Your cat has no fur. Hairless cats may have a bit of "peach fuzz" but should otherwise be hairless.



LaPerm

LaPerm coat (Lplp)

Your cat has curly fur similar to LaPerm fur. Their fur is soft with a textured feel, and is made of light, springy curls. They also will have long, curled whiskers. Carries non-LaPerm gene.

They will have a notable "zorro" mask around the eyes and bridge of the nose of their self color, and may appear to have thicker markings overall. They will have a less reddish, brownish, or creamy ground color than a standard tabby, so they may appear somewhat desaturated by comparison. Charcoal will not act on red-based cats.
