We all love cats, right? Otherwise why would you be on the internet. We all love their cute little faces when they look up at you with those wide eyes and longing looks. Purring and rubbing themselves against your leg looking for some more cat food.

But what do you really know about your cat? I don't mean when it goes missing for days and comes back with a glint in its eye, the smell of dead mice on its fur and a coat hanger in its tail. Those are private cat activities that us humans should not delve into.

I mean like how many front and back paws it has or whether it can taste sweet things or not? Well now's the time to get with the program and find out.

It's an interactive video where you play the piano by using the timeline. Brought to you by Instrumentube. Under their profile page they've also got an electric guitar, bass guitar, upright bass and shaker. You can start your own band on YouTube!

I can imagine a world in the not-too-distant future where all human activity will be carried out on YouTube. Stay with me on this one. We'll watch entertainment videos there, play music, video-games, use it to communicate, eat, breath, dance the horizontal tango. Everything.

It'll be like the Matrix except it'll be full of 14 year-old vloggers decrying their lot in life, and fat people who can't leave the house taking the Pizza Roll Challenge who taste of heart attacks and diabetes. I can't wait.
