Owner of 'World's Oldest Cat', 31, Attributes Long Life to Mineral Water
Leslie Greenhough, from Stockport, believes his 31-year-old tortoiseshell cat Millie may be the world's oldest living cat. He attributes her longevity to a decade of Buxton mineral water, a diet including prawns, salmon and treats, an indoor lifestyle, and attentive care. Millie originally belonged to Leslie's late wife, Paula, who died from COVID-19 in 2020. Leslie hopes to have Millie recognized by Guinness World Records but lacks sufficient documentation to prove her birth date.
