Advice for KC and other interested parties.

Dear Kattycat,
You ask for suggestions for rousing your family when they lie abed too long.
Ping pong balls are the answer! You can make a very gratifying noise with a ping pong ball if you persevere.
Figaro, the British Blue cat who preceeded me, before they realised a house rabbit was the perfect companion animal, once frightened off a burglar during the night by playing with his ping pong ball. My lot heard him bashing it around in the kitchen and put the house lights on. Off shot the intruder and Figgi received great praise.
Another idea is one of those food bowls with a timer. It could be primed to open early just for you if they insist on having a lie in. That could also make quite a din if you try to toss it around to open it before its time. I often throw my dish around to let them know when it is empty.
Good luck,
Harvey
