I don't think the cat-toast dimorph would levitate. I think it would just hang suspended a few inches above the ground and spin--cat-side, toast-side--caterwauling and dripping.
laws of toast says when you drop toast, it always lands buttered side down. when a cat is dropped, it always lands on its feet. if you strapped buttered toast on the back of a cat and then dropped the cat, both laws defy each other, so the cat would not fall, it would levitate?
