Cats may have their own chemical ID cards, study finds

 A groundbreaking study reveals that cats employ specific fatty acids in their urine, which act as chemical identifiers for each feline. These branched-chain fatty acids leave a persistent scent trail, allowing cats to recall individual urine aromas long after they’ve faded. The findings imply that the kidneys may help store these scent molecules, offering new insights into how cats communicate and recognize one another within their social networks. A groundbreaking study reveals that cats employ specific fatty acids in their urine, which act as chemical identifiers for each feline.
