"Leaving the head of a rabbit on a footstool is irresponsible and dangerous."
A Beginner's Guide to Transfiguration, on how this spell can go wrong[src]

There exists a Transforming spell that transfigures a rabbit into a footstool. When improperly preformed, however, only the rabbit's head may form. In this state, the creature is considered dangerous, and Emeric Switch considered leaving such a creature in this state irresponsible, suggesting in his book A Beginner's Guide to Transfiguration to restore it with a counter-spell like Reparifarge.[1] The counter-spell for this is the Lapifors Spell.
