Grumpy cat uncensored! Xherdan the 'naked' Sphynx cat wins legions of online fans for his wrinkly skin and permanent scowl (12 Pics)

This grumpy looking hairless cat is taking the internet by storm thanks to his permanently frowned expression.

Five-year-old Xherdan, a Sphynx cat who lives in Switzerland with owner Sandra Filippi, 45, has a face that many would balk at.

But not Sandra, who said Xherdan immediately 'stole my heart' when she found him up for adoption online.  

Xherdan now has nearly 5,000 followers on Instagram after Sandra began posting pictures of his wrinkled skin and grumpy face.

The scowling kitty is even shown posing for photos in costumes and jewellery.

Sandra said: 'When I first saw him, he immediately stole my heart. His wrinkled pink skin, as fine as a peach, his turquoise eyes, as blue as the ocean. I was in love.

'He makes me and other people laugh all the time and that's the most beautiful thing there is.

'I am so incredibly proud. He is just so unique.

'Sphynxes take up a lot of time, they always want to be where their humans are.

'He watches everything and always wants to know what we are up to.

'I am so incredibly proud of him.'
