I also had a cat that was always peeing on my bed and pillow. I kept blamming it on the dog's until I actually caught the booger. She had a litter box and would use it, well she would use it until I would leave my room. Needless to say she is now an outside cat.
And on the kid's wanting to keep the mice that are suppose to be food, whenever I hear my youngest daughter say "Awww...that's a cute mouse" it is allways the first to become BP food.
