An old cat's guide to scaring your human

I must thank my elderly house mate, Smudge, for this piece of late night entertainment.

1. 
   Make sure you are last seen near the cat door after dark on a cold night.
2. 
   Do not reappear in your favourite night time spot at the usual time.
3. 
   Do not respond to being called.
4. 
   Do not investigate people walking around the house and section with torches and cat treats calling you by name.
5. 
   Stay silent and hidden in your chosen spot all night, no matter how many times your owners get up and turn the lights on.
6. 
   Reappear a little later than is your custom for breakfast. For best effect do this from a room that they have searched 4 times already.
