The record is currently held by 27-year-old Flossie from London, but as Rosie's owners are waiting to hear from the Guinness World Records she might soon be knocked off the top spot ...
Rosie was born on 1 June 1991. Rosie's paw-rent rescued the "fluffball" when she was a kitten and has only visited the vet twice in her life. Lisa Blissett said Rosie "is lovely" and mostly enjoys "eating and sleeping" these days.
Rosie is just six years off the age of the oldest cat to have ever lived - Crème Puff from Texas lived to the grand old age of 38 according to the Guinness World Records.
The record breaking feline was born on 3 August 1967 and lived until 6 August 2005, cared for by his owner Jake Perry in Austin, Texas, in the United States.
