In your cat’s brain, there is a rhythmic neural oscillator that operates on repeat, which sends a message down to your cat’s laryngeal muscle making them twitch. This causes them to vibrate between 30 and 150 vibrations a second. When this occurs, there is a separation of the vocal cords when inhaling and exhaling causing the feline vibrato.
Purring could have several meanings
Lions roar, because it serves an evolutionary purpose, but if that is the case then why do cats purr? We; as humans, have often thought that purring was simply a signal of pleasure from your cat, a contentment with their lot in life. Though contentment does seem to cause cats to purr, they also purr when they are being threatened or if something frightens them. People smile when they are nervous, happy, or when they get something they desire, cats appear to be the same though that is largely a mere speculation.
If you own a cat, you know that when they want something, you will know beyond a doubt, and they will not stop pestering you until they get what they are after. Cats will add an additional vocalization to their purr in order to elicit the desired response from humans, whether it is to fix them food or give them attention. Added to their usual 25Hz purr, they will utilize a very high frequency meow to get you to move quicker, they learn to do this very early as it tends to be somewhat annoying to the human ear and gets their goals accomplished faster.
