Hahaha loved that story Bill!
Cats are extraordinarily clever at getting what they want. Our little Minty used to scale up the kitchen shelves like a mountaineer, then reached down and tip the packet of special treat biscuits onto the floor. This enabled the lot of them to gorge themselves silly, then puke up their excesses, leaving delightful piles of sick for me to find in the morning.
They reminded me of teenage lads out bingeing on lager and coming home to spend the night being sick into a bucket!

SmokeyPokey could always find a way to push up the slider which locked the catflap. We eventually changed the system and he was stumped. He howled and yowled every night until he twigged we weren't giving in.
One needs nerves of steel to deal with Siamese cats!
