Smokey, 12, is now in the Guinness Book of Records with her incredible purr.
She has been known to purr as loudly as 90dB at home, which is as loud as a hairdryer.
Owner Ruth Adams, from Northampton, said: “Smokey and I are very excited at being awarded the Guinness World Records title for the loudest-purring cat.
“It’s either adorable or annoying, depending on what mood you’re in, and it’s very loud.
“When I’m on the phone friends ask what the noise is and they can’t believe it is coming from a cat.”
Craig Glenday, Guinness World Records editor, said: “It’s incredible to think a cat’s purr can be as loud as a vacuum cleaner.”
A statement from Guinness World Records said: 'We are pleased to announce that Smokey, a 12 year-old female British short-hair cat, has been recognised as having achieved the loudest purr by a domestic cat at 67.7 dB (LA peak).'
Its editor Craig Glenday added: 'Guinness World Records is a veritable cat-alogue of fantastic felines, and Smokey is a welcome addition to the family. It's incredible to think a cat's purr can be as loud as a vacuum cleaner. Most domestic cats purr at around 25 decibels.'
It seems the only time Smokey goes quiet is when she is asleep. 'She has always been very vocal and purrs nearly all the time,' said Ruth .'She even manages to purr while she eats.'
