These vibrations occur at a frequency of 25 to 150 Hertz, which is within the range that promotes healing and reduces stress in both cats and humans. The exact mechanism behind purring is not fully understood, but it is believed to be controlled by the cat's central nervous system. Purring is often associated with contentment and relaxation in cats, but they may also purr when they are in pain or distress. **
