This cat takes 'grumpy' to a whole new level

Hide your souls, this cat looks like he's out to steal them. Atchoum is the internet's latest cat sensation, and the kitty couldn't look more sinister.

According to his Facebook page, Atchoum's long, irreverent head hair is the result of a hormonal condition called Hypertrichosis, which causes excessive hair growth. While that doesn't explain the crazy eyes, the cat seems to be pretty normal otherwise.

The Canadian feline, whose name means "sneezy" in French,  can be seen on his social media accounts, playing with toys, lounging in the sun and rolling on the ground.

Evil or not, Atchoum's constant, angry expression may just put "Grumpy Cat" to shame.
