Cats may have their own chemical ID cards, study finds
Researchers have discovered that cats use a unique set of 13 branched-chain fatty acids in their urine as a durable chemical 'calling card' for individual identification. This system allows cats to recognize each other even after long periods, providing insight into feline social communication.
Why it matters
Understanding animal communication mechanisms contributes to the broader scientific knowledge of chemical ecology and mammalian behavior.
It seems there exists an established yet hidden cat calling system. According to scientists, cats identify one another through a shockingly durable chemical "calling card" made from 13 unusual fatty acids in their urine. Thus, feline friendships might have to do more with their identification than consistent meetings.Cats rely heavily on scent to learn about one another and often, they gather this information from urine and other odour marks left behind in their surroundings. These chemical traces can continue communicating long after the animal that produced them has moved on.But this leaves us with a puzzle. Many odour molecules evaporate, break down or change over time. If a scent is consistently evolving, how is an animal still able to determine who originally left it?
