Cross-Species Transfiguration is a branch of Transfiguration in which one animal is Transfigured into another. It is a basic O.W.L. spell and is taught to fourth-years and above at Hogwarts School of Witchcraft and Wizardry. The spell seems to be easier if the animals in question have similar names, e.g. guinea fowl to guinea pigs.

Although humans are creatures too, it is harder to Transfigure a human into an animal, especially Self-Transfiguration, and so this is not taught until sixth-year. There is a distinct difference between an Animagus and Self-Transfiguration, the difference being that an Animagus is a rare wizard with the ability to transform into an animal at will. Self-Transfiguration is simply Transfiguring oneself into another form, and so a wand is necessary to perform the precedure, and can be performed by any wizard skilled enough.
