Flossie, a British domestic short-haired tortoiseshell cat, has turned 30 years old, extending her Guinness World Record as the world’s oldest living cat.

Born on December 29, 1995, Flossie reached the milestone birthday in 2025, further cementing her place in record books. Her age was officially verified by Guinness World Records in November 2022, when she was confirmed to be 26 years and 316 days old. At the time, her age was estimated to be equivalent to around 120 human years.

Flossie’s early life began in a feral colony near St Helens Hospital in Merseyside, England, where she was rescued as a kitten. Over the years, she lived with several owners before eventually coming under the care of the UK animal welfare charity Cats Protection.

In 2022, Cats Protection arranged for Flossie to be adopted by Victoria Green, who lives in Orpington, England. The charity worked closely with veterinarians to verify Flossie’s date of birth using historical records, enabling Guinness World Records to formally certify her age.

At the time of her record confirmation, Guinness World Records noted that Flossie was deaf and had limited eyesight. Despite these age-related conditions, she was otherwise considered to be in good health. The organisation said she maintained a stable daily routine that included regular meals, extended periods of sleep and gentle play.

Flossie is currently recognised as the oldest living cat in the world and ranks among the seven oldest verified cats in recorded history. While other cats, including Creme Puff, are documented to have lived longer in the past, Flossie remains the oldest confirmed feline alive today.

Her 30th birthday further extends her record and highlights advances in animal care, nutrition and veterinary support that can contribute to longevity in domestic cats.
