It seems Fifty Shades of Grey isn't just a human phenomenon.
Cats? They love a bit of Christian Grey.
In fact, armed with a tie, a six pack and a ball of string, some kittens (with a helping hand from The Pet Collective, we assume) have made their very own version of EL James' erotic adaptation.
But you'll be glad to know they steer well clear of any inappropriate behaviour. It's mainly just a lot of purring, a few cat toys and a kitten being incredibly distracted by the fact it's just grown an impressive six pack.
If you think Fifty Shades might be a bit hardcore, this is fluffy cat cover is definitely one for you...
