A 71-year-old man, Leslie Greenhough, says his tortoiseshell cat Millie is the world’s oldest living cat. According to the report, Millie is believed to be 146 in “human years,” based on age conversion methods used by cat owners and pet age guides. The articles describe Millie’s diet as including salmon, prawns, chicken and tuna, which Greenhough says supports her health and longevity. The reports present Greenhough’s account of Millie’s age and do not include independent verification from official animal registries. They also do not provide details on how Millie’s exact birth date was determined. Overall, the story focuses on the owner’s claim about Millie’s lifespan and the feeding routine the owner attributes to her continued well-being.
