Cats, Dog considered, were clearly a lot tougher than lost souls.

Consider the situation. There you are, forehead like a set of balconies, worrying about the long-term effects of all this new 'fire' stuff on the environment, you're being chased and eaten by most of the planet's large animals, and suddenly tiny versions of one of the worst of them wanders into the cave and starts to purr.

Everyone's heard of Erwin Schrodinger's famous thought experiment. You put a cat in a box with a bottle of poison, which many people would suggest is about as far as you need to go.

Our garden was debated territory between five local cats, and we'd heard that the best way to keep other cats out of the garden was to have one yourself. A moment's rational thought here will spot the slight flaw in this reasoning.

In fact, the mere act of opening the box will determine the state of the cat, although in this case there were three determinate states the cat could be in: these being Alive, Dead, and Bloody Furious.

Curiosity may have killed the cat, but her's curiosity could have massacred a pride of lions.
