Strange AnimalsThe Himalayan is a deliberate hybrid of the Persian and the Siamese, a cat with the Persian's long, flowing coat and cobby body structure combined with the Siamese's colorpoint coloring and vivid blue eyes. It was the product of a systematic breeding experiment begun in the 1930s by Virginia Cobb and Dr. Clyde Keeler of Harvard, who set out to understand the genetics of colorpoint coloring by crossing the breeds.
The result of their work, and of subsequent breeders' refinements, is a breed that delivers the Persian's visual drama (the flowing coat, round face, compact body) in a range of colorpoint patterns that the Persian cannot produce, with the Siamese's distinctive blue eyes making the colorpoint markings even more striking.
The Himalayan occupies an ambiguous position in pedigree cat classifications. CFA classifies the Himalayan as a division of the Persian rather than a separate breed, reflecting the view that the Himalayan is essentially a colorpoint Persian. ACFA recognizes the Himalayan as a separate breed, while TICA places it within the Persian breed group. This ambiguity in registration reflects the fact that the Himalayan is genetically a Persian that carries the colorpoint (cs) gene, and the two breeds are essentially indistinguishable except for color.
What is not ambiguous is the health profile: the Himalayan inherits every health concern of the modern Persian, including all of the consequences of extreme brachycephaly.
Origin and Development
The deliberate development of a colorpoint Persian began with Virginia Cobb and Dr. Clyde Keeler's experiments at Harvard in the 1930s, published in 1936. Their goal was academic, they wanted to understand the inheritance of the colorpoint pattern, but the cats they produced were beautiful, and other breeders recognized the commercial potential.
British breeder Brian Sterling-Webb independently developed the cross over about ten years in the United Kingdom, where the GCCF recognized it in 1955 as the Longhaired Colourpoint. In North America, the Himalayan name was adopted, referencing the colorpoint pattern of Himalayan rabbits and other animals from the region (the cat breed itself has no geographic connection to the Himalayas).
CFA recognized the Himalayan as a championship breed in 1957 but subsequently reclassified it as a division of the Persian rather than a separate breed, a classification it maintains today, resulting in CFA show classes for Persian (solid) and Persian (pointed/Himalayan) rather than separate breed classes.
Physical Characteristics
The Himalayan has the full Persian body type, a cobby, compact, heavily boned cat with short legs, a broad chest and a round head. Combined with the colorpoint coloring and blue eyes, this creates a distinctive look that is unmistakably its own.
| Characteristic | Details |
|---|---|
| Build | Cobby, compact, heavily boned, Persian type |
| Head | Round, large, flat-faced (brachycephalic) |
| Eyes | Round, large, vivid blue |
| Coat | Long, flowing, dense double coat |
| Points | Seal, blue, chocolate, lilac, red, cream, tortie, lynx |
| CFA status | Division of the Persian breed |
The coat is the same full Persian coat, long, dense and with a woolly undercoat that mats severely if not maintained daily. This is the primary practical difference between the Himalayan and the Balinese, which has a similar colorpoint appearance but a non-matting, easier-care semi-long coat.
The colorpoint pattern deepens with age and in cooler environments, as in all colorpoint breeds. Blue point Himalayas develop richer blue-grey points in cold conditions, the body color remains relative pale throughout.
The Same Health Concerns as the Persian
The Himalayan's most important health consideration is that it inherits the Persian's full suite of health problems associated with brachycephaly, and these are significant.
Polycystic kidney disease (PKD) is among the most critical hereditary health concerns. The PKD1 dominant mutation from the Persian foundation is present in Himalayan cats, and DNA testing of both parents is essential before any Himalayan purchase. Prevalence of PKD in untested Persian-derived populations has historically been extremely high, some studies report 40% or greater in tested cohorts before DNA screening became widespread.
Brachycephalic Obstructive Airway Syndrome (BOAS) results from the Himalayan's flat face. Narrowed nostrils, elongated soft palate and reduced nasal passage volume create varying degrees of respiratory compromise. Surgical correction is available for the most severe cases.
| Health Concern | Details | Testing |
|---|---|---|
| PKD (polycystic kidney disease) | PKD1 dominant mutation from Persian | DNA test, essential |
| BOAS | Brachycephalic airway compromise | Clinical assessment |
| HCM | Hypertrophic cardiomyopathy | Echocardiogram |
| Epiphora | Chronic tear overflow; facial staining | Daily management |
| Skin fold dermatitis | Facial fold moisture trapping | Regular cleaning |

Temperament
The Himalayan personality is primarily Persian-influenced, with the Siamese contribution manifesting more in the colorpoint genetics than in the temperament. Himalayans tend to be calm, placid and gentle, more sedentary than the Siamese or Balinese, less demanding in their social needs.
The breed is well-suited to quiet homes and to owners who appreciate a decorative, affectionate cat that does not demand constant engagement. Himalayans enjoy gentle interaction and petting but do not typically vocalize with the persistence of the Siamese or follow their owners with the intensity of the Abyssinian.
Activity level is low to moderate. The breed is content with a comfortable perch and regular gentle interaction. Interactive play is enjoyed but not required at the intensity needed by more active breeds.
Daily Grooming Requirements
The Himalayan's Persian coat requires daily grooming. Without daily combing with a wide-toothed metal comb, the coat develops mats within days, mats that must be cut out if allowed to develop. The daily grooming commitment is the central practical consideration of Himalayan ownership.
Face cleaning is also a daily requirement, identical to the Exotic Shorthair: the facial folds, inner eye corners and nose leather area accumulate tear staining that must be wiped clean daily to prevent hardened, difficult-to-remove dark staining.
Prospective owners who cannot commit to daily grooming should seriously consider the Exotic Shorthair, which has the same Persian face with a manageable short coat.
Frequently asked questions
This depends on the registry. CFA classifies the Himalayan as a division of the Persian breed, not a separate breed, the distinction being colorpoint (Himalayan) vs. non-colorpoint (Persian/Exotic Shorthair). TICA places the Himalayan within the Persian breed group, while ACFA treats it as a separate breed. In practical terms, the Himalayan is a Persian carrying the colorpoint (cs) gene from Siamese ancestry, producing colorpoint markings and vivid blue eyes that the Persian cannot produce.
Polycystic kidney disease (PKD) is caused by an autosomal dominant mutation (PKD1) inherited from the Persian side of the Himalayan’s ancestry. It causes progressive cyst formation in kidney tissue, eventually leading to kidney failure. Even one copy of the mutation causes disease. Before DNA testing became available, PKD prevalence in Persian-derived breeds reached 40% or more.
Both parents of any Himalayan kitten should have documented PKD1-negative DNA test results, this is non-negotiable from a health standpoint.
Many do. The Himalayan’s flat, brachycephalic face creates the same BOAS (Brachycephalic Obstructive Airway Syndrome) problems as the Persian: narrowed nostrils, elongated soft palate and restricted nasal passages. Snoring, noisy breathing and exercise intolerance are common. The severity varies, some Himalayans breathe normally, others require surgical correction. Buyers should observe both parents breathing at rest before purchasing.
Daily grooming is required; this is not optional. The long, dense Persian coat with its woolly undercoat mats severely within days if not combed daily with a wide-toothed metal comb. Additionally, the flat face requires daily cleaning of facial folds, inner eye corners, and the area around the nose leather to prevent hardened tear staining. The daily grooming commitment of the Himalayan is the single most significant practical consideration of the breed.
Himalayan cats are recognized in a wide range of colorpoint patterns: seal, blue, chocolate, lilac, red, cream, tortoiseshell and lynx (tabby) points in various combinations. Pointed Himalayans have vivid blue eyes regardless of point color. The body remains relatively pale, with the colorpoint areas (face, ears, legs, tail) showing the deeper color, a contrast that deepens with age and in cooler environments.
Yes. The Himalayan’s low activity level, minimal vocalization and calm temperament make it one of the more apartment-suitable longhaired breeds. The breed does not require large spaces and is content with a comfortable environment and regular gentle interaction. The main practical challenges are the daily grooming commitment and the veterinary costs associated with managing the brachycephalic health issues that commonly affect the breed.
