A feline's purr is usually a soothing, content sound - but not in the case of Smokey - the cat whose purr sounds as noisy as a Boeing 737.
The sound she produces can reach an incredible 92 decibels - same as kind you'd experience watching a Boeing 737 coming in to land.
While most cats produce 25 dB of sound, Smokey produces 80 decibels even from five feet away, reports the Daily Mail.
"She even manages to purr while she eats. The only time she is quiet is when she is asleep," said Ruth.
"It's either adorable or annoying, depending on what mood you're in. You don't even have to stroke her to start a purring session. Often she'll do it for no reason."
There's a category for noisiest cat in the Guinness Book of World Records, but it's not full yet, said a spokesman.
"If Smokey can purr at over 80dB it would be an astonishing feat," he said.
Diana Johnson, of Northampton Cats Protection, who has met Smokey, said, "I have never heard anything like her purr in my life. It can drown out your conversation. It is very unusual and I've never found a cat with a purr that is anywhere near as loud."
