You must know Simon’s cat

A contender for the most famous feline on the web, Simon’s Cat is the star of five online films that have been watched by 36 million viewers across the world.

This moggy has its own book, and now the animator Simon Tofield’s creation has its very own app, ‘Purrfect Pitch’. Costing £1.19, it invites players to play piano with the cat, who will blow raspberries and yowl if you get notes wrong. It also lets you record your musical efforts which can be played back at your leisure.
