Animal Deathmatch

I am finding myself in an attic, where the deathmatch will take place. My opponent is there as well, but I can't remember who she is, more than it's a she. We gather up our allies. She has a sneaky cat, I think it's black and brown. I take one of my childhood toys, some sort of dog or bear, and I magically enhance it to get long fangs and it becomes big and not really menacing. It still feels like a stuffed animal. We talk and then start to fight. I grab the cat by its neck with both hands and I twist its head off.
