A cat in Britain soon could be crowned the oldest feline in the world.

Rosie is a fluffy tortoiseshell — and will celebrate her 32nd birthday on June 1 with her owner Lila Brissett, 72, who took her in as a kitten in 1991, according to SWNS, a British news service.

People have told Brissett to contact the Guinness Book of Records to confirm that her cat is indeed the world's oldest mixed breed feline. 

The current holder of that honor is a 27-year-old cat named Flossie from Kent, said SWNS.

Rosie has only ever visited a veterinarian twice, according to her owner.

Brissett, a retired housewife from Norwich, Norfolk, told SWNS, "This beautiful thing was handed to me in a cane basket as a kitten in 1991 — and the rest is history."

Brissett said the cat only visited the vet to be spayed in the '90s and then "five years ago, to get antibiotics for a cyst on her head."

Added Brissett, "She's quite a character. She's still got all her teeth."

Brissett said she was approached by animal rescuer in the ‘90s. 

Rosie the kitten needed rehoming after her first family couldn’t keep her once they realized their daughter had allergies.

Brissett had previously rescued an abused cat and a stray dog — so she happily welcomed Rosie into her home, SWNS reported.

Rosie is a cross between a ginger tom and a rag doll, "giving her a gloriously fluffy tail."

She lives indoors in Brissett's ground-floor apartment — and is fed Purina One cat food daily "or she'll kick up a fuss," said Brissett.

The Guinness Book of World Records says that the oldest cat alive currently is 27, according to its records.

Flossie was born on Dec. 29, 1995, as verified in Orpington, in the United Kingdom, on Nov. 10, 2022.

It added that the oldest cat ever was Creme Puff of Austin, Texas, who was born on Aug. 3, 1967, and lived until Aug. 6, 2005 — 38 years and three days.

When asked why she thought Rosie had lived to such a ripe old age, Brissett said, "Care and attention? Good food? I don’t know. All my animals seem to live to a good age. Rosie sleeps by the window all day and, like clockwork, she will have some food and use the litter tray."

She added, "There's no need for an alarm clock. All she does is eat, sleep, use the litter tray and repeat," as SWNS reported.

She also said, "I often have to check if she's still alive and breathing. I'm worried about the day she crosses over the rainbow bridge. She'll leave a big void."

"I'll miss her when she goes," said Brissett. "But I'll never have her put down."

A spokesperson from the Guinness Book of World Records said, "We would encourage Lila [Brissett] to make an application for Rosie via the Guinness World Records website for our Records Management Team to review," SWNS reported.
