Waddy the Cat is celebrating a milestone birthday.

The British feline turned 27 years old on March 6 -- which could make him one of the oldest cats in the UK, the Times & Citizen reports.

"He's like a little old man, really. He gets up, goes out, comes in, has his food and then goes back to sleep," Ann Munday, Waddy’s owner, told the BBC.

Munday adopted Waddy in 1986. She says he was the runt of the litter, who she nursed back to health, according to the news outlet.

“I’ve always had cats, but he is an absolute dream and he has been a fantastic companion since my husband died 13 years ago. He was a tiny and very poorly little thing, so it’s a miracle he has survived,” Munday told Metro UK.

Waddy, who is named after a British beer, is a fussy eater who prefers fish and chicken to his cat food.

And despite some minor health problems, Waddy is going strong. His vet, Gill Monsell, told the BBC that he is "certainly the oldest cat on its books at the moment."

Waddy isn’t the only age-defying feline.

According to the Guinness Book of World Records, the oldest cat ever was Creme Puff, an American cat who lived until the age of 38 in Austin, Texas.
