Some master vampires have the ability to develop moitié bêtes or animals to call. That is, a master vampire can develop psychic powers over some specific type of animal, which also allows him or her to form a binding psychic connection with a single matching lycanthrope or other animal-related creature like a lamia. The term "animal to call" can refer to either this particular bound individual, or the whole group of animals ("wolves are his animals to call"), or even any shapeshifters that match the animal in question. On the other hand, the term "moitié bête" seems to be more strictly limited to the bound individuals.
