Everyone loves an optical illusion, but the latest visual tease to leave the internet confused is something a little different.

Furry pet Atchoumfan has left Twitter baffled after a user posted a picture of him saying: "Her - 'do you have a dog or a cat?'. Me - 'I don't know'."

The image of the enigmatic creature has been retweeted over 12,000 times and liked over 22,00 times as users tried to figure out what kind of animal they were looking at.

Barb Leflar Jackson couldn't figure it out at all, saying: "Yeah, what IS that?" while FreebieBean joked it was an owl, adding: "Whatever it is I want it."


Stillchip was sure they were looking at a feline, saying: "While the ears are barely visible, the eyes are a dead giveaway. The pupil shape is cat all the way."

Noonefollowsme agreed making the point that "the eyes never lie", adding: "Those are cats eyes":.

Summersanz joked "it's a Cog Dat" while ‏JulieCTaylor said: "Definitely a dog. Very cute!"

Eventually, the person behind the Twitter account revealed that the creature is in fact a cat.

The pet is already internet famous in its own right, not just for being half-cat-half-dog.

He has over 162k followers on hisInstagram page where he is described as a 'young male Persian with hypertrichosis. I'm hairy not scary!!'

The owner of Atchoum regularly keeps followers up-to-date with what the feline is doing and he can often be seen wearing a funky-coloured bow tie.

He also appears to have been featured in magazines, campaigns and has even been in shows.

Atchoum also has a website dedicated to him. It says: "Hello and bonjour! I'm Atchoum, the hairy but not scary Persian kitten from Quebec, Canada. I purr with a French accent.

"Some people say my wild furs and intense amber eyes make me look like a dog, an owl, a mad scientist, a Gremlin, Lorax or the Grinch but I'm happy to be me.

"I love life and love sharing my adventures every day with you!"
