Blue Persian Cat: The Color That Won the First Shows
The dilute that ruled the first cat shows: blue Persians headlined Westminster in 1899 and America's first champions in 1900-1902. The gene, the look, the history.

"Blue" in cat language is a soft slate grey, and on a Persian it is the breed's most historied coat: the dilution gene softening black pigment across the fancy's biggest canvas, paired with the same copper eyes as its parent color. The mechanism is standard feline genetics (the dilute allele, recessive, acting on black), which is why blue kittens appear from black-carrying lines and why the color breeds true once paired.
The Victorian and Edwardian receipts
The blue Persian's claim to fame is documentary: 's own archive carries an 1899 Westminster show photo caption, and the earliest documented AMERICAN show winners of 1900-1902 ran heavily to blue and silver Persians: the color was the height of fashion when the cat fancy invented itself, on both sides of the Atlantic. Queen Victoria's blue Persians are part of the legend layer; the show records are the checkable part, so the records are what we print. For the breed's deeper origin story, the history page keeps the labels on.
Living blue, practically
The dilute coat often reads plusher than dense colors ('s own texture note runs the other way for dominant colors like black: the dilutes tend woollier, which can mean marginally more comb time in molt season); tear staining shows moderately; and no market source we read prices blue above other colors today, whatever Victorians paid. The fashion cycled; the cat stayed excellent.

Frequently asked questions
What is a blue Persian cat?
A slate-grey Persian: the dilution gene softening black pigment, with copper eyes by standard. One of the breed's oldest show colors.
Why are they called blue and not grey?
Cat-fancy convention older than the registries: the cool-toned dilute of black has been "blue" since the first stud books.
Are blue Persians rare or expensive?
Neither today: a founding color, unrestricted everywhere, no premium in any market source we read. In 1900 the answer was different, which is the fun of it.
Do blue Persians have different coats?
Often slightly woollier than the dense colors (the registry's own texture-by-density note runs silkier for black and red), which can mean a touch more combing in molt season.

This is information, not veterinary advice, and it cannot tell you what is wrong with your cat. Our rule is a simple one: if something is wrong with your cat, call your vet, and call an emergency clinic if it is out of hours. Nothing you read here is a reason to wait.
Medical information applies to every reader. Prices, legal duties and common practice do not: unless stated otherwise, they are given for the United States, and they differ in the UK, Canada and Australia, and often between states or provinces. Check with your own vet and your own local authority.
