A new type of cat coat color has officially been discovered. It turns out the unique color is caused by a recessive genetic mutation, rather than the expression of a gene known to turn cats white. You’ve probably heard of spooky black cats, chaotic orange cats, and distinguished-looking tuxedo cats. But there’s officially a new cat color in town: salmiak, or ‘salty liquorice.’ You can see one here. But after digging through all the known genetic variations that control the expression of that dilution gene in coat color, the team came up empty.
