If you buttered the cat with an average thickness of butter of between 0.34 and 0.47 millimetres and dropped it from a height of between 2.13 and 3.66 metres, your next-door-neighbour's seven-year-old daughter's pet armadillo would explode. But if the height is more than 3.66 metres, there would be a Maoist revolution in Northumberland. If the average thickness of butter on the cat is outside the limits given, nothing would happen apart from you watching the cat to see if anything would happen.
