The nine-year-old tabby cat was given the nickname by workers at the Blue Cross pet charity after they noted her bum measured ten inches across.
Kit K's real name is Phoebe but it seems she'll be keeping the moniker Kit Kardashian for now…
Her foster owner Belinda Smith, a volunteer at the charity, said: "I have been looking after her for two weeks now. A lady from Blue Cross brought her over to my home and when she came out of her cage I said 'Oh my goodness, she's a big girl'.
"A colleague had already come up with the name 'Kit Kardashian' after Kim's famous bottom - there is a striking resemblance."
Kit's a gorgeous cat but at 8.4kg she is twice the size she should be. Now, she's on a diet to help her slim down and reach a healthier weight.
Belinda says poor Kit currently struggles to move and is hoping her size doesn't put potential owners off.
"I hope we are able to find her a home. She tries to run around but struggles. But she has got such a pretty face and is such a lovely cat, I'm sure she'd make a new owner very happy."
