- Millie only drinks Buxton spring water and enjoys foods like salmon and chicken
- Her cautious, shy personality may have helped her live longer
- Special care during UK heatwaves keeps her comfortable in old age
What happened
Millie, a tortoiseshell cat born in 1995, recently celebrated her 31st birthday, making her one of the oldest cats in the world. She originally belonged to Leslie Greenhough’s late wife and has been cared for by Leslie since. Over the past decade, Millie has enjoyed a diet that includes natural Buxton spring water, salmon, prawns, chicken, and tuna, as well as plenty of treats and cuddles.
Leslie shares that a local water pipe repair led to a switch from tap water to bottled Buxton spring water, after dirty water came from their taps. This change seems to have contributed to Millie’s extraordinary longevity. They marked her birthday with a special bowl of chicken, celebrating the milestone with pride and affection.
Why it feels good
Millie’s story is a heartwarming reminder of the power of love, care, and attention in extending the lives of our pets. Her gentle, shy personality has mellowed into a cautious but relaxed companion who brings comfort and joy to her family. Leslie expresses pride in Millie’s resilience and longevity, noting she is the equivalent of 146 years old in human years.
The cat’s loving home environment and thoughtful care, combined with her unique diet of pure spring water and fresh food, make her a symbol of thriving old age in pets. Millie’s story sparks hope and admiration, inspiring pet owners everywhere to consider how simple, attentive care can make a lasting difference.
What to enjoy or watch next
Millie’s owner hopes to see her recognized in the Guinness Book of Records as the oldest living cat, a tribute to her extraordinary lifespan. Her story also invites celebration of other senior cats, including Flossie, currently the oldest verified cat at 30 years old, also from the UK. Pet lovers might enjoy checking in with friends to discover who has the oldest feline companions among them.
As Millie continues to receive special care during the UK’s heatwaves—such as fans and ice cubes in her water bowl—pet owners can take inspiration to keep their own animals comfortable during extreme weather. Together, stories like Millie’s celebrate the joy and magic of long lives filled with gentle care and companionship.
