EMS codes for cats

2015.05 nagrody.jpg

Easy Mind System, or EMS for short, is a code used to quickly identify cat breeds and color varieties. The code for color, pattern, or any other feature is always the same, regardless of race. When describing a cat, we first use the three-letter breed abbreviation, always written in capital letters, followed by lowercase letters and numbers describing the color, pattern, and other characteristics of the cat.

FIFe recognized fur designs

A

After the color letter, in the EMS code describing each cat, there is a number indicating the fur pattern associated with the amount of white or brindle.

White cats are sometimes interesting cases. Black and white bicolor will be described as "n 03", but the Turkish Van, since it always carries the amount of white that corresponds to the van, does not have to be marked with the code "01" in the description. It is simply described as "TUV" to denote the breed, and then the color and eye color are selected, since this is a breed in which we have more than one eye color. (Code for an indefinite amount of white, "09", is reserved only for those breeds in which it is approved, namely Maine Coon, Norwegian Forest, Rex and Manx cats.)

A specific case among Siamese cats is the whole body white cat, formerly known as Foreign White. The EMS code for this cat is "SIA w 67."

A

  • 01 - van

  • 02 - harlequin

  • 03 - bicolor

  • 04 - mitted - only used in ragdolls

  • 05 - snowshoe - only used with Snowshoe

  • 09 - undefined amount of white (less than 1/4)

  • 11 - shaded

  • 12 - shell / chinchilla

  • 21 - unspecified brindle

  • 22 - classic brindle

  • 23 - tiger stripes

  • 24 - spotted

  • 25 - ticked

  • 31 - Burmese color

  • 32 - Tonkinese color

  • 33 - Himalayan type, color point

A

The coding of particular types of tabby can be a problem, especially for point varieties or breeds, or for vans and harlequins, because in these varieties only small parts of the body can be seen in the tabby pattern. Such cats are identified by the number "21", which indicates that the cat is tabby but it is not possible to tell what type of tabby it is.

In the case of other breeds or color varieties where the type of brindle is clearly visible, we enter the number that defines its pattern. The British black tabby will be described as "BRI n 22". British silver spotted cat will be described as "BRI ns 24." The "ticked" tabby patterns are so far reserved only for Abyssinian / Somali and Oriental Shorthair cats. Abyssinian / Somali cats are all "ticked" brindle, therefore there is no need to add "25" to the description in EMS code form; but for oriental cats that have different colors, the brindle pattern should be marked. So a chocolate ticked oriental cat would be labeled "OSH b 25."

Designations of individual eye colors

The next element of the EMS code is the numerical description of the eye color which must be used for breeds assessed in different classes according to the eye color. For example, in the case of white British cats, similar to Persian cats, we have color variants with blue, orange, and two-color eyes. The blue color of Himalayan (point) cats, which is the result of a gene in the Siamese breed, is different from that of white and blue-eyed cats. Therefore, blue eyes of Himalayan cats have a separate code. The orange color of most Persians and Brits is also different from the yellow eye color of Burmese cats, which is why it has a different code.

  • 61 - blue eyes

  • 62 - orange eyes

  • 63 - eyes of different colors

  • 64 - green eyes

  • 65 - eye color of Burmese cats

  • 66 - eye color of Tonkinese cats

  • 67 - eye color of Siamese cats


The eye color code may be omitted for a breed that is by definition only one color, such as Burmese cats. The same applies to Siamese and some Persian or British cats, in the case of black, blue, cream, red, etc. varieties, as all of them must have orange eyes by the standard. However, the eye color should be marked for white cats - Persian, British, and some other breeds. So the blue eyed white Persian should be labeled "PER in 61", the orange eyed white British would be defined as "BRI in 62" and a white Maine Coon with two colored eyes would have the code "MCO in 63."

The eye color must also be coded for the silver tabby Persians as they are now judged in two different grades depending on the eye color, orange or green. Thus, a silver tabby Persian with orange eyes would be described as "PER ns 22 62." The EMS code for a green-eyed silver tabby Persian will be "PER ns 22 64." (After the breed designation, "PER", are followed by "n" meaning black, "s" sewing silver, 22 or classic tabby, and finally "62" to describe eye color).

Codes for special breeds


These are codes for breeds that have specific characteristics.

The tail codes, used only for Manx cats, and their longhair counterpart, the Cymric, are used to determine the length of the tail.

  • 51 - rumpy - no tail

  • 52 - rumpy riser - a tiny elevation on the bone at the end of the spine

  • 53 - stumpy - vestigial tail no longer than 3-4 cm

  • 54 - longies - normal or almost normal tail (such cats can be used in breeding, but do not participate in shows)


Ear codes are codes that identify the type of ear for two breeds. The first is the American Curl, both in the longhair and the shorthair versions, which, while having their ears wrapped themselves, can produce offspring with straight ears. The second breed, so far not recognized by FIFe, is the Scottish Fold, again in both the Shorthair and the Shorthair versions. long-haired, which can also give offspring with straight ears.

A

  • 71 - straight ears

  • 72 - wrapped ears

  • 73 - folded ears


By following all of the above rules, you can create your cat's EMS code yourself without looking at its pedigree. The non-genetic EMS system has been developed to be easy to use and logical. With a little practice, any cat breeder should be able to use the EMS code just as fluently as their mother tongue.
