Why Do Cats Purr?

Any cat lover will tell you that one of the primary appeals of these animals is their ability to purr. In addition to the softness and cuteness, a cat’s purr adds immensely to its appeal because human beings find that sound to be very comforting and inviting.

Even after all these centuries and scientific advancements, it is still not entirely clear why cats purr. It does seem to indicate contentment and relaxation, but could there be another reason as well?

Science has shown that cats may also purr when they are frightened, hungry, or injured. We also know that some large species of cats, such as cheetahs and cougars, can also do it. Some believe that in addition to soothing those around them, cats may choose to purr as a way of soothing themselves during periods of stress.

Cats can also do it to comfort other felines. There are numerous reports of cats laying beside injured felines and purring, apparently as a way of providing comfort to their friend.

Interestingly, they may also do it to promote bone and tissue growth/repair. You might have heard about how high frequency sound can aid in tissue regeneration. Domestic cats commonly purr at a frequency of 26 Hertz, which falls within that sound range. So kitty may also be helping herself sometimes when she turns up the volume.

However, for most people, the sheer appeal of a purring cat boils down to nothing more than how comforting it can be. Much like a dog’s wagging tail, the purring of a cat indicates contentment, happiness, and love in their purest forms. It is the sort of welcoming presence that makes life easier at the end of a long and hard day. It also represents the sort of selfless, uncomplicated love that rarely exists between human beings.
