or snoring :]
Mostly, cats purr when content and satisfied. It's like a human making the sound "ahhhh" after a filling meal. Cats also purr when stressed or in pain.
The reason cats purr is because its their natural sound. Just like how we have our voice.
All cats can have different sounds when they purr from loud purring that sounds like a locomotive to sounding like a pigeon. Cats have muscles in their voice box that vibrate to cause the purring sounds and most cats purr when happy.

No. a cat's purr is an involuntary action, their bodies natrually do it without any effort. its basically like breathing, we don't have to think about it to do it. often purr when they're being stroked or played with. Humans can make a purring sound with our tongues or some can breathe in and make a purring sound with our throats but it isn't the same as a cat's purr.
Cat purrs can be good for you. Just like when you smile, the sound of a cat purr can bring you joy. The sound of a cat purr also lowers your stress levels, therefore making cat purring a medical and mental benefit.
actually thay kind of sound like "VAROOM!"
Yes, they can. It is now thought that all cats, even "big" cats that can roar, can purr. Big cats, with their specially-designed throats, can only make a purring sound when exhaling which is called "chuffing", and not in a constant stream like other cats.they cannot but they can chuff they can purr,but only on the ex hale. I don't think wild cats can purr; but I did hear that one can, the cheetah.
All the cats do, domestic along with the big cats.
