Cat Purring

Even though not every species of cats purr, domestic kittens as we know them are born with purring ability. We believe that cats typically purr when they are content, thus, we associate purring with a happy cat.

However, cats also purr when they are distressed or in pain. Female cats will purr while giving birth. She does this to sooth her kitties and to comfort herself.

Cats produce the purr through intermittent signaling of the laryngeal and diaphragmatic muscles during both inhalation and exhalation.


Some researchers believe that the different sound frequencies of purrs mean different things. For instance, a slow frequency may be indicative of a cat's ability to conserve energy.
