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.

Oilbirds display distinct travel patterns when seeking fruit in tropical forests. Some birds return to their main cave nightly, while others venture out for days.

Researchers tracked twenty-one birds using devices to record their movements and flight times.
