Whereas if the cat weighed the same as the toast...or the toast is the same weight as the cat...

Why am I saying toast?? It's buttered bread, not toast...I must have something for toast...

So if the cat and the piece of buttered bread were both the same weights...

If they are the same weights then surely they will spin around in the air trying to be the one to land first...until of course the cat eats the toast off its back and plummets to the ground, landing lightly on its feet.
