I used to live in a flat which had woodchip wallpaper - every dodgy builder's favorite decorating option as it tends to hide any defects in the wall with random nobblyness. All went well until two kittens called Smudge and Cholmondeley moved in and discovered quite how delightful the stuff was to use as a claw sharpener. In a few short weeks my walls went from nobbly to shaggy.

They grew out of it after a year, and it was surprisingly easy to train them to use a scratching post. But it still meant I had to redecorate two rooms.

Pedants will notice that the skirting board only appears in the first frame.
