The average lifespan of an indoor cat is 13 to 17 years, but a feline in the United Kingdom is about to turn 28 — or 140 in cat years.

Cola the black cat was born in November 1985 at a time when “Back to the Future” was topping the box office and the “Miami Vice Theme” was a number-one single.

Now she’s about to be crowned Britain’s oldest feline, a title she’ll take from a 27-year-old cat named Wadsworth who was thought to be the country’s oldest cat until recently.

Born at the bottom of a wardrobe, Cola was adopted by Mary Goldsmith and has since had three litters of kittens.

Goldsmith says the secret to Cola’s extraordinarily long life is exercise and lots of treats.

“She loves her luxuries like cream, custard and salmon. She always has a good nibble from my plate as well as her own cat food,” she told the Daily Mail. “And I’ve got children, grandchildren and great grandchildren who come over to play with her and keep her busy.”

Although she suffers from arthritis these days, Cola has always been healthy. In fact, she’s been to the vet only once — to get spayed.

“She has lived to such a grand age,” Goldsmith said. “Perhaps she really does have nine lives? She is a lucky black cat, that’s for sure.”

Cola may be the oldest cat in Britain, but she still has a decade to go if she wants to hold the Guinness World Record for oldest cat. A cat named Crème Puff from Austin, Texas, is the current record holder. She lived for 38 years and three days.
