Something further to consider.
If you drop a cat from a height of say 10 feet, it will always fall on it's feet. But if you drop a piece of buttered toast from the same height it will always fall with the buttered side down.
So here is the problem, if you tie a piece of buttered toast onto a cat's back and drop it from the same height will the buttered toast land butter down i.e. with the cat upside down, or will the cat land on it's feet i.e with the toast butter side up?
