Domestic cats identify their fellow felines by sniffing urine, thanks to a distinctive chemical profile unique to each individual, according to a study published in a scientific journal.
The research aimed to uncover the mechanisms of chemical communication in cats, which rely heavily on smell to recognize friends, strangers, and social relationships. Scientists analyzed urine samples from multiple cats and found clear differences in the composition of chemical compounds between individuals.
The results show that, akin to the “scent signatures” seen in many other animals, each cat has a distinct urinary makeup, precise enough for others to tell them apart. This finding explains why cats often spend time thoroughly sniffing urine marks in the environment before reacting—it is how they gather information about the identity, sex, and physiological state of the animal that left the mark.
The authors hope the findings can help better understand feline social behavior and improve ways to manage and care for pets living alongside humans. The study opens deeper avenues into how cats use chemical signals to build social maps within their communities.
