A cat who resembles a cross between Albert Einstein and Grumpy Cat has become an online sensation after his 'unique' look caught the eye of Instagram users。
Pompous Albert has racked up tens of thousands fans, thanks largely to his angry face and unique coat。
The frowning feline even has a hint of evil leader about him - he is a Selkirk rex, a breed of cat known for its wild, tufty fur。
Due to his white-grey colour, Albert, who lives in Sagebrush Fine Art in Salt Lake City, Utah, was named after the famous physicist, who was known for his wild, grey hair。
The seven-year-old cat spends his days mulling around the gallery, with owners Mike and Susan Singleton snapping him in the likes of drawers, on printers and just generally looking annoyed at the world。
And as he continues to become more popular, Mike and Susan hope to make donations to local shelters from any money they make。
Mike said: "The overwhelming interest in Albert have made us wonder if it's real。
"He can glare without moving and so it's intimidating."
He added: "But he loves when equipment in the office is being used - the shredder, fax, printer - he runs over and attacks them。
"Albert is a real sweetheart - when he is petted he has a loud purr, but it's definitely on his terms."
