In her weakened, primal state of mind Mina was instantly focused on the sound of footsteps nearing her. Her fox ears twitched and her bloodshot, golden eyes were immediately focused on the male that approached her cage. She didn't recognize him, nor did she know what he was. Human, supernatural, she would feed on anything right now. If she could get just a bit of blood in her system she would probably regain some kind of sense, but right now she would devour anything that moved.
The moment Cassius neared the cage she had torn out of her human skin and into that of her fox form, locking her jaw around one of the bars of the cage in an attempt to get to her prey. Her neck was chained down as well as all her limbs and all her tails, so she couldn't get really far. Her jaws just about locked around the iron bar, but she couldn't get any further than that.
