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.

While some sources claim that the sound of a cat's purr has healing properties, there is limited scientific evidence to support this claim. More research is needed to fully understand the potential health benefits of a cat's purr.
No, humans cannot purr like a cat. Purring is a unique vocalization produced by the rapid contraction and relaxation of muscles in the larynx of a cat, creating a continuous sound. Humans do not have the anatomical structure or ability to produce this specific sound in the same way that cats do.
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.
Purr words would include words like, "home," "national security," "trust," and "freedom fighter." Snarl words would include words like, "terrorist," "liar," "greed," and "foreign." The way a person or group is labeled (with a purr or snarl word) often depends upon who is doing the labeling.
