As they move, they dilate and constrict the glottis – the part of the larynx that surrounds the vocal chords – and the air vibrates every time the cat breathes in or out.

Marjan Debevere is a cat shelter photographer in London who is currently studying for a degree in feline psychology. She draws the comparison between her cat Luigi – a stray who followed someone in to their office and was subsequently taken to a shelter – and Archie, who “moved in from next door” and became part of the family. The study of cats’ behaviour and communication has lagged behind that of dogs, which are usually more willing participants, especially if there is a reward of food involved. “We’re just beginning to understand it and there are more unanswered questions than answered,” says Gary Weitzman, a veterinarian and CEO of the San Diego Humane Society. “While the purr does generally represent contentment for cats, it can also express nervousness, fear and stress.

This nonverbal form of communication tells you that life is good and that your cat is very happy with the current situation.

The frequency may also serve to reduce pain, ease breathing, and build muscles, among other health benefits.
