why do cats purr?

When our felines become soft, reassuring bundles of purring joy, we both hear and feel it. However, have you ever wondered why they purr and what produces this characteristic sound?

It is thought that the basic function of purring is to allow the kitten to communicate with his mother that things are well. A kitten is able to purr by the second day of life. Even though he can’t meow and nurse at the same time, he can purr and nurse. And the mother will often purr back, probably in reassurance.

For a variety of reasons, purring is an integral part of the feline communication system, and the meaning of the purr changes as the cat matures. Some felines purr to indicate pleasure and contentment. But did you know that frightened cats that are not feeling well may also purr.

Some feline behaviourists theorise that when cats purr under stressful circumstances, they are reassuring or comforting themselves, much as humans may sing to themselves or hum when they are nervous. A scared cat may possibly purr to communicate submissiveness or non-aggressive intentions.

Old cats may purr when they play or approach other cats, signalling that they are friendly and want to come closer.

However, whatever the reason our felines purr, we all know it is one of their most endearing qualities.
