No, but there is a mental condition in which someone believes they are an animal.
Nothing, 'cause humans don't turn onto werewolves
No. Werewolves do not exist. Inter-species transformation is impossible.
Well, for one thing they aren't real. And if they were, they would be part human. Werewolves are believed to be humans that turn into blood sucking vampires, furry crooked humans, and maniacs by the full moon. And wolves dont do that.
It's the same for everyone it's inherited. If you mean Leah then she just has it in her blood. When vampires are around the ones who have the gene in their blood turn to werewolves. But really there is no werewolves in twilight, in breaking dawn it turns out that they really are shape shifters, werewolves would need full moon.
They don't. Werewolves are fictional.
they eat them
Basically you have your vampires vs. werewolves and humans in between. The Cullen's are vampires, the Black's are werewolves and the Swan's are humans.
vampires can actually turn into werewolves. its the truth (but folklore) Vampires can trans there body to werewolves as werewolves can trans themselfs to vampire. its called camouflage. vampires tend to turn themselves as werewolfs for disguise.
The same that are with dogs and humans.
You can't. Werewolves do not exist, and it is impossible for anyone to become one.
I suppose you could but it probably would be considered cannibalism (werewolves were human once)
Nobody really knows for sure. There is no proof to real werewolves but there might be. Don't get your hopes up because who knows if there really are werewolves.
