Ksenia, a Scottish Fold feline from Russia, is what thousands of internet users are calling the world’s cutest cat.

Ksenia, a charcoal moggy, first appeared on YouTube in December 2011, but she has become an online sensation in the past 48 hours, attracting more than 355,000 views.

The cat is so cute that some fans have even suggested she’s an elaborate and hi-tech animatronic toy – while others have offered to buy her.

Ksenia does nothing out of the ordinary in her YouTube debut, scampering around playfully on the back of a chair.

But thousands have flocked to the site to see her flawless fur, bright orange eyes, panting puppy-like tongue and impossibly perfect face.

There’s been so much interest in this little kitten, her owner logged onto the site today to field questions from fascinated fans.

One user likened Ksenia to a Antonio Banderas’ adorable animated cat in Pixar’s Puss in Boots; while another offered $1,000 to buy her.

Her owner jokingly agreed, before replying: “Jokes. I will never this do it.”

Other fans have even speculated Ksenia is the result of some clever CGI technology – or an animatric doll.
