"Slow Zombie Transformation?" I am SO there...

[SoylentOrange]

Honestly, if they've got that much time, I could see them bolting her jaws shut and putting caps on all her fingers and toes so even if she was reduced to a fairly mindless state they could still keep her mostly as a pet without worrying about spreading the infection through biting/scratching. I mean, once she's undead they don't need to feed her anyways, right?

I can see this movie having not a happy ending, but not a sad one, either; bittersweet, perhaps.
