Overview of the Calico British Shorthair
The British Shorthair is renowned for its iconic plush coat, round face, and stately presence. While the ‘British Blue’ is the most recognized variety, these cats are bred in a spectacular array of colors and patternsâincluding the rare and eye-catching calico. Calico refers to a tri-color pattern of white, orange (red), and black (sometimes with cream or gray), produced by a unique genetic combination mostly found in females.
With their owl-like amber or copper eyes, stocky build, and thick, luxurious fur, calico British Shorthairs are both visually striking and deeply endearing as companions. Letâs explore what makes these cats singularly special.
Breed History and Development
The origins of the British Shorthair date back centuries as one of the United Kingdomâs oldest cat breeds. Selective breeding after World War I incorporated traits from various other breeds to revitalize the population and expand color and pattern options.
- Key contributing breeds: Persian, Russian Blue, Karthauser, and Chartreux cats were among those used post-WWI to strengthen lines and diversify markings, ultimately resulting in the robust, plush British Shorthair we know today.
(Fact: Multiple breeds contributed to todayâs variety in the British Shorthairâs coat and patterning.) - Coat Variety: The British Shorthair now comes in over thirty coat colors and patterns, with associations recognizing classics such as blue (gray) as well as tabby, bicolour, tortoiseshell, and calico.
Appearance and Calico Genetics
British Shorthair cats are famous for their teddy bear-like shapeâsolid, cobby frame, broad cheeks, large round eyes, and a thick, dense coat. The calico pattern, meanwhile, is especially prized for its genetic rarity and vibrant visual contrast.
Physical Characteristics
- Body: Medium-to-large, muscular build with a broad chest and powerful stature
- Head: Broad, rounded with pronounced cheeks and a strong chin
- Eyes: Large, round, often copper or gold; sometimes blue or odd-eyed in colorpoint varieties
- Coat: Dense, plush, short yet luxurious, offering a “crisp” textureâone of the breed’s hallmarks
- Tail: Thick at the base, rounded tip
All About Calico Coloring
Calico refers to fur that is primarily white with patches of black and orange (or their diluted colors, cream and gray). This pattern is created by a complex interaction of genetic factors on the X chromosome, making most calico cats female.
- Why Are Male Calico Cats So Rare?
The genes controlling orange and black fur are both carried on the X chromosome. For a cat to show both (calico), it needs two X chromosomes (XX). Since male cats typically have only one (XY), calico males can result from a genetic anomaly (XXY), which is exceedingly rareâabout one male in every 3,000 calicos.
(Fact: Male calico British Shorthairs are considered “unicorns” in the cat world, often sterile due to their unusual genetics.) - Variations in Calico: ‘Dilute Calico’ patterns (cream, gray, and white) are also possible, as are mosaic or split face calicos, adding to their individuality.

Personality and Temperament
