Scooter, from Texas, who was born on March 26, 1986, died just days before Guinness World Records confirmed he had been the world's oldest cat. The title passed to tabby Corduroy, 26, from Oregon. A Guinness World Records spokesman said Mrs Brown will have to provide evidence of Henry's long life, including a vet proving his age and pictures through the decades, for him to be officially recognised as the oldest and steal the title.
The average life expectancy of a house cat is 12 to 15 years. The oldest cat ever to have lived was called Creme Puff, who died in 2005 aged 38 (169 in cat years).
The formula for calculating cat years equates the first two human years of life to 25 cat years, and each additional year counts as four cat years.
