Pavlov's person

Slave one makes me wear a collar with a bell in the vain hope that it stops me from catching birds. Who has time for bird catching in between eating and sleeping and eating? Most cats find a way to stop the bell when they want to but I have found a use for making as much noise as possible (apart from the standard of waking slaves in the middle of the night whilst having a vigorous grooming session). Humans being the selfish things that they are, have put the doorbell too high up for a cat to use. But a quick shake of the collar and slave one is usually opening the front door within seconds. Much better than going around the back and trying to squeeze through the "cat door". As if all doors aren't cat doors.
