Some quantum mechanics have suggested that an inverse of the Cat-Toast device would be possible. The inverse would consist of a piece of buttered toast glued butter-side-up to the stomach of a cat. The cat would attempt to land on its legs but the non-buttered side of the toast would prevent it. Likewise, the buttered side of the toast would want to land, but the cat's back would be unable to hit the ground. However, while this would seemingly have the same effect as a regular Cat-Toast device, it would actually have a quite different effect where the cat and toast would be crushed into singularity. This would occur because unlike a traditional Cat-Toast device where the cat and toast repel opposite each other, the inverse Cat-Toast device has the cat and toast repel towards each other. This squeezes the cat and toast into an infinitely small piece of matter, much like a black hole. The cat, however, would soon escape due to its nine lives (which are replenished during such quantum discrepancies) and the toast would get burned anyway from the massive amounts of heat released during the compression process.
If you glue the toast's buttered side to the cat's top, you'll create a device which will ram into the ground as hard and fast as possible.
If you force a cat to swallow the toast whole it will turn inside-out so that the toast can hit the ground.
