When cats are very happy, they make a purring noise. It's a deep-ish sound that comes from the back of their throat.
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.
All the cats do, domestic along with the big cats.
A cat purrs when it is happy, which usually happens when they are shown affection. Depending of the personality of the cat, they will voluntarily purr when they are, for instance, being pet, so they are happy. Some cats that like their solitude, will often run away after a minute, or might just run away the minute they come in contact with you. Usually, cats will do this, and might just growl or hiss to show that they do not lie this. So mad cats will not purr and happy ones will. They purr of their own free will, and have a choice to do so. If you have ever seen a cat roaming around or going somewhere and purring? This is because the cat is happy. Maybe they had some treats, or maybe they just had a good nap. How many mad cats do you see purring? None, that's right. Because cats only purr when they are content and happy. Or sometimes, a cat might be happy and not purr. This also happens. All in all, a cat's purring is voluntary.

If the cat seems content, and/or maybe flexing it's front paws in a massaging manner, then I believe what you are referring to is the cat purring. Cats pur when they are happy and content. :) HMT8
You can tell by their body language, sounds such as purring or hissing, or sometimes if you look at their face you can tell when they are happy or sad
The scientific name for a domestic cat is Felis catus. A cat that is purring does not have a different name than a cat who is not purring. A purr is just a characteristic of all domestic cats and some larger cats as well.
not really. if they are purring, they might tread. but normaly cats don't.
Purring, meowing, pretty much every sound they make any other time except with a few added to communicate with her kittens. :)
By purring or rubbing up against you.
Yes they do. By stropping you and purring and laying on or next to you.
