His owner, who has concealed her identity and location in the U.S. and uses the pseudonym J.H Lee told Time: ‘My friends loved looking at pictures of him.
‘We started the first Facebook page as a joke.’
His adorable appearance is the result mainly the unusual haircut he was given following an accident — his fur was so long and tangled that it had to be shaved off.
Lee said: “The groomer said they wouldn’t even be able to get a brush through him.
“I was really upset when I heard that.
“But when I picked him up, I found he was actually really cute that way.”
