Catfight!!

If your cat becomes engaged in a fight with a stray cat outdoors, break it up immediately. To break up a catfight, toss a glass of water on the animals or place a bunch of coins in a can and shake it near the cats. Once the fight has ended, collect your animal and search him for wounds.

If your cat has a wound as a result of a fight, wash the wound immediately with mild soap and water (and a drop of lavender oil if available). This should kill the bacteria and quicken the healing process. If the wound does not heal or if it becomes inflamed, see a vet immediately—it is likely that your cat needs antibiotics.
