Here’s some enjoyable science! A collaboration between the College of Helsinki in Finland and the pet genetic testing firm Knowledge Panel has recognized the genetic mutation behind the not too long ago found “salty licorice” coat colouring seen on some Finnish cats.
The putting new cat coat sample nicknamed “salty licorice” is popping heads within the feline world. With its uncommon mixture of black fur sprinkled with white hairs, the look resembles the favored Nordic sweet that impressed its identify. Now, scientists say this eye-catching sample isn’t only a quirky color variation—it’s the results of a newly recognized genetic mutation, providing contemporary perception into how cats’ coats develop.
Salty Licorice or Salmiak Cats
The putting “salty licorice” cats with their distinctive white fur sample have been first noticed within the Finnish village of Petäjävesi greater than 15 years in the past. They got the identify “salmiak” or “salty licorice” by researchers because of the distinctive coat colouring’s resemblance to the favored Finnish sweet—black licorice dotted with white salt.

The identify “salmiak” or “salty licorice” comes from the favored Finnish sweet: black licorice dotted with white salt.
Uncommon Cat Coat
Salty licorice cats look much like tuxedo cats however with distinctive colouring: ombré strands of fur that begin out darkish on the base earlier than fading to white. These felines have darkish markings on their faces, however their fur turns into more and more white in the direction of the again of their our bodies, ending with the tip of the tail being primarily white.
New “Salty Licorice” Cat Coat Sample Linked to Genetic Mutation
Geneticist Hannes Lohi and his researcher workforce on the College of Helsinki—which homes a biobank of 5,000 blood samples from greater than 40 feline breeds—have been curious how these cats bought their distinctive look, so that they studied their DNA, with cat homeowners and breeders providing their cat’s DNA for the analysis.

The scientists’ research, revealed within the journal Animal Genetics in Might, discovered {that a} novel gene mutation is liable for the distinctive fur sample.
Cat Genetic Mutation
The workforce known as the gene variant w-sal, for salmiak. Every of the salmiak cats had two copies of the recessive gene. A couple of of the opposite cats had one copy (not ensuing within the distinctive salty licorice color), whereas the remainder of the regular-coloured cats had none.
The gene is a variant of the KIT proto-oncogene (KIT) gene, which is “related to an absence of melanocytes within the pores and skin and hair follicles,” the researchers discovered. Gene variants that give cats and canines white fur can typically trigger deafness, although that doesn’t appear to be the case with w-salmiak.
Feline Genetics
Lohi says the primary purpose of this work, “is to know the molecular and environmental causes of feline issues.”
Are salty licorice cats going to be the subsequent huge factor?
“It’s potential that breeders will select to develop a inhabitants of salty licorice cats,” says Lohi. “Nevertheless, the well being of the salty licorice cats must be adopted in additional element to substantiate the absence of any colour-related well being points.”
