I don't think it's that easy to interpret this song without having a look at Sia's others lyrics. What I believe are two themes occurring throughout her lyrics are: 1. she seems to have a double personality (she-wolf is she + wolf) and 2. she permanently feels under attack (chase, hunt, kill are words from this song) and she must absolutely resist. If we consider Chandelier: 1. the double personality of the party girl who leads a crazy night life full of alchohol and sex, but then in the morning feels the shame; 2. she swings from the chandelier but she won't look down or open her eyes (scared), holds on for dear life as she feels in danger, she wants to resist, not to fall down. In Elastic heart the double personality is well shown by 1. the little girl first fighting in a cage with a man, but then she tries to lead him out of there and make peace. She fights for peace. She's at war but she wants peace at the same time; 2. she's got a thick skin + elastic heart and she thinks she can resist attacks, but the blade may be too sharp even for her. Or again in Titanium she's under attack (you criticize) but all your bullets ricochet 'cause I'm made of titanium (=I've got a thick skin). As a conclusion, I see a woman with a double personality who feels weak when personality A (the one with yellow eyes) overcomes personality B (I can't compete with the she-wolf that's in me); B tries to defend herself in all ways but knows that that may not be enough to save herself from the she-wolfs that lives inside herself. B even asks for information about A in She-wolf - what do you see in those yellow eyes? Quite complicated: a psychiatrist might help Sia, I think. Sounds like she might have really been under attack (abused?) when she was a child (little girs and little boys are the protagonists of the other videos I quoted). Hope all that will stimulate your interpretations
