That's it - you can shut down YouTube and turn off the computer because the internet has now officially seen it all.

A cat called `Juan' riding a bike while wearing a tiny sombrero may be one of the most bizarre videos seen on the web.

It's certainly one of the cutest.

As one internet user wrote: "Everything past this is invalid".

The video appears to have been shot some time ago in Asia and has recently been posted on a number of sites including YouTube and LiveLeak.

It features a rather dapper tortoiseshell moggy wearing a natty little sombrero with a strap under his chin.

One website claims the cat's name is Juan.

`Juan' balances his front paws on little handlebars attached to the back of a bike which is being pedalled by its owner.

When we first see `Juan' and his owner, their bike has stopped at a pedestrian crossing and the cat is wagging his tail slightly as someone holding a video camera approaches and begins filming.

`Juan' then licks his paws and wobbles slightly as its owner pedals away from the crossing.

As the bike moves off, `Juan' moves his head slightly to the right so he can get a better view of where they're heading.

The internet is well known for its love of cat videos - there's plenty out there.

But this `Juan' appears to be a whisker above the rest.
