British kitty Bella has broken the record for loudest purr by a domestic cat (living) after her sounds were measured by a Guinness World Records adjudicator working with an acoustic engineer. Cat mom Nicole Spink raves about her 14-year-old feline saying "She purrs all day long! If there's food around, or cuddles, she always purrs. Also when watching TV she likes to be loud with television.” At 54.59-decibels, Bella’s purr is as loud as a refrigerator and vacuum cleaner.
