A cat has laid a claim to having the loudest purr in the world because she makes noises as loud as a Tube train. 12-year-old Bluey has a growl which is louder than most cats can miaow, and has reached a maximum of 93 decibels - more than the official world record holder. Despite her fearsome sound, Bluey is said to be gentle and loving, and is currently in a rehoming centre in Cambridge looking for a new owner. Scroll down for video . Noisy: Bluey the cat could have the loudest purr in the world, according to staff at a rehoming centre . Claire Thomas, from the Blue Cross charity, said: 'We've never had a cat in our care with a purr as loud as Bluey's. 'We thought it would be fun to see just how loud it is so we recorded it and it reached 93 decibels at its loudest, which is very impressive. 'Though she's surprisingly loud she's a lovely cat and we'd hate for it to stop her being rehomed.' Bluey went to the centre after her elderly owner had to go into care, and staff were shocked when they stroked her and she started growling like a dog. Measurement: The loud cat has been clocked at more than 90 decibels using a sound meter app . Homeless: Bluey is looking for a new owner and is currently living at a centre in Cambridge . Her purr, which is almost four time louder than the average cat, has been keeping other animals awake at night. Mis Thomas added: 'Bluey purrs all the time. She just has to see someone and she starts purring. She purrs when she's playing and she purrs when she's eating. 'We think Bluey is a little deaf but that doesn't stop her enjoying life. She's such a happy, friendly cat and she will make such a loving companion.' The noisy cat is well above the official world record holder Smokey, who was recorded at 67.7 decibels in March 2011, but her purr has not yet been officially certified. Contender: Bluey must now register with Guinness if she is to win the official world record . A spokesman for Guinness World Records said: 'We're intrigued by Bluey's talent and we would welcome an application from his owners so we can look into their claim. 'We would love to hear from them and strongly suggest they make an application for this record via our website.' However, Bluey's new owner may have to take precautions, as scientists say noise levels over 90 decibels can cause hearing loss over a prolonged period.
