Vemos em Harry Potter ea Ordem da Fênix que McGonagall faz com que seus alunos de Transfiguração pratiquem o Charme de Fuga (Evanesco) em camundongos (e eles já fizeram caracóis):
“As I was saying, the Vanishing Spell becomes more difficult with the complexity of the animal to be vanished. The snail, as an invertebrate, does not present much of a challenge; the mouse, as a mammal, offers a much greater one. This is not, therefore, magic you can accomplish with your mind on your dinner. So — you know the incantation, let me see what you can do. . . .”

... e Ron consegue desaparecer a maior parte do mouse:
“Well, it’s a start,” said Ron, holding up a long, wriggling mouse tail and dropping it back into the box Lavender was passing around.

Isso levanta a questão de é possível desaparecer os seres humanos? Vimos que mamíferos (como nosso simpático ratinho) não estão isentos de desaparecer. Isso vale para humanos?
