Only the bad cat owners. The good ones can predict when there’s mischief in their eye.

I’ve only been scratched once in two years and it was an accident due to a fairly unlikely farcical comedy scene.

Essentially, if you’re sat on a wooden chair (which can amplify sounds), and you have a nervous cat pinned on your lap, as you apply a vial of flea treatment to his neck, I recommend that you do not suddenly and loudly pass wind.
