Cat Kidney Lipids Create Durable Urine Signatures
TL;DR Summary
Researchers found domestic cats store 13 branched-chain fatty acids in kidney lipid droplets, forming a reservoir that slowly releases a distinctive urine fingerprint. This stable chemical signature remains detectable for about a day and varies by individual, helping cats identify one another over time and offering potential tools for odor management and scent-based tracking of wild felids.
