Why do cats purr?

Today’s post is all about purring. Cats often purr when they are being petted, when eating or when they are generally relaxed. Unfortunately, Brucy doesn’t purr often – she purrs only when she knows she will get chicken or when she is lying on the radiator.

How does it actually happen? Animals produce the purring sound by using their vocal cords and larynx muscles to dilate/constrict the glottis, causing air vibrations. As a result, the air inhalation and exhalation, produces the purring noise.

Interestingly enough, cats are not the only animals that purr.

According to Wikipedia (yes, I know, not the most reliable source), “viverrids (civet, mongoose, genet), bears, badgers, hyaenas, rabbits, squirrels, elephants” and lemurs also purr while eating.

Speaking of squirrels, you must watch this adorable video about a squirrel that grew up with cats and as a result learned to purr and thinks it’s a cat! Too adorable!
