Why do cats purr?
The Real Answer
Cats purr in more than one context, so a purr is not a simple happiness meter. The exact sound-production mechanism is still being refined: experiments published in 2023 showed that excised domestic-cat larynges can produce purr-frequency oscillations without active neural input or muscle contraction, suggesting the vocal-fold tissue itself can generate much of the low-frequency sound under airflow. That does not prove living cats never use muscular control, and claims that purring evolved to heal bones remain speculative.
A cat can purr because it’s happy, hungry, stressed, or in pain. That’s not communication. That’s your car making the same noise for “everything’s fine” and “pull over immediately.” And the cat’s just sitting there looking at you like you should know the difference.

Purring feels like the closest thing a cat has to a status light, which makes people want one clean translation. The problem is that cats can purr in comfortable, stressful, and painful situations, so the rest of the cat still matters.
