The owners of a cat with a purr so loud that it's been compared to a Boeing 737 landing have made a bid for the record books.
Smokey's owner Ruth Adams borrowed specialist sound equipment from a local college to record the attempt, reports the Daily Mail.
The record bid, at their Northampton home, saw the 12-year-old's purr reach 73 decibels - 16 times louder than the average cat.
Now Mrs Adams is waiting to see if it will be enough to be recognised by Guinness as the world's loudest purring domestic cat.
She said: "Guinness has very strict criteria and the college has been very helpful in supplying the specialist recording equipment needed to measure Smokey's purr and for arranging the official witnesses.
"Smokey is actually quite camera-shy so I was very conscious not to upset her during the record attempt so we kept it all kept very calm and low-key.
"We are very grateful to the college for stepping in to help us attempt the record and now just have to wait patiently to hear the final verdict."
Witnesses on hand for the attempt were Daventry MP Chris Heaton-Harris, veterinary nurse Kaye James, Diana Johnson from Cats Protection, and British Airways captain Alisdair Tait.
Ray Meadham, curriculum manager in music at Northampton College, said: "You don't get asked to help out with a world record attempt every day so of course we jumped at the chance."
Smokey first came to the world's attention last month, when a sound meter measured her purr at an incredible 92 decibels, as loud as a lawnmower or a plane landing.
