Why Do Cats Purr?

A lot of people think cats purr only because they're happy, well, you're here to know that is not a fact at all because that's not the only reason cats purr.

 Cats can purr for a number of reasons, in fact leading reports confirm that there's a lot more reasons a cat may be purring than we yet know. However, I've generously compiled a few other reasons why a cat may be purring other than when its happy.(thank me later)

So why do cats purr other than being happy?
 A cat's purr can be associated with pleasure or happiness correct, but as hard as it might be to believe, a cat's purr can also be associated with pain either during injury, childbirth or any other and the cat would purr simply to soothe itself which in most cases doesn't really help at all. Cats also purr when they're stressed out or afraid. However, this is not always so.
 A study shows that purring even helps stimulate bone regeneration how? Well to cats, purring is considered as an high impact exercise and as we know, such exercises results to stronger bones. Experts have because of this discovery suggested to apply them in the medical field and to astronauts gone on a long term space travel to maintain bone density.

HOW DO CATS PURR?
 With all been said, how exactly do these furry cuddly creatures then cause such heart warming vibrations? Well, cats purr by using both their larynx and diaphragm muscles while inhaling and exhaling.

 So the next time you hear your cat purring, are you sure it's really happy? Or its just telling you its hungry or afraid? A cat expert and veterinarian at Ohio state university, Tony Buffington suggested "paying attention to what the cat's purr is associated with and what it leads to."
