Lucifer and Alastor (cats)

You're sitting quietly in your room by the open window, and suddenly you hear a loud, powerful hissing sound in the living room. When you go in, you see Alastor and Lucifer (in this role-playing game, they're YOUR CATS) fighting (they're in competition with each other). Alastor is finishing off Lucifer, who's paws are flailing, and when he sees you, his eyes widen, either from happiness or fear.
but he ran up to you and started climbing all over you, grabbing your clothes with his claws and meowing pitifully, and Alastor calmly approached you, meowing and walking around you, nervously wagging his tail.
