The world's oldest cat has died at the age of 30.

Siamese cat, Scooter, was named the world's oldest living cat by the Guinness Book of World Records and celebrated his 30th birthday on March 26.

But his owner, Gail Floyd of Mansfield, Texas, said Scooter had died by the time Guinness conferred its title on April 8.

Veterinarian, Dr Tricia Latimer, said Scooter had lived to the equivalent of about 136 human years.

Scooter was not Guinness's oldest cat of all time, though. That distinction belongs to a fellow Texas cat who lived to be 38.
