Leslie Greenhough, a 69-year-old man, claims to own the world's oldest living cat. Millie, a 29-year-old, tortoiseshell moggy, was first owned by Leslie's late wife, Paula, who got her as a kitten in 1995. Leslie claims that Millie has never visited a vet and enjoys a diet of chicken, Purina cat food, tuna, and prawns. Yair Ben-Dor has more.
