Can only become a wolf on the astral. And Dav, sort of like porphyria could explain vampirs back then?
And very painful. You would probably pass out from the pain or even die.
Yeah...breaking your bones and reshaping them just seems like something that you would get over the pain pretty quickly. Not to mention changing where your internal organs are. What a wonderful ride it must be.
Skull, neck, spine, ribs.
And yes you would. Just because we have similar organs doesn't mean the size and placement are the same.
