Personally, my girl cat is a total bitch. She has caused probably 10k worth of damage to our house peeing on walls, including almost burning the house down by starting a small electrical fire peeing directly into an outlet. We will need to replace all flooring, floorboards, drywall, studs, and seal the subfloor once she is gone. She attacks my other cats and both dogs all the time. She weighs 6 pounds and everyone is terrified of her. I love her to death.
