It should be easy to keep a cat happy. All you have to do is bow to your cat’s will and do everything it asks you to do. Then everything should be all right as long as you remain a faithful servant for the rest of your life.
Of course, there’s more to keeping a cat happy. Make sure you set aside lots of play time together. Keep your cat entertained at all times and provide plenty of space such as giving your whole house to your cat while you sleep in the street. The more ways you allow your cat to dominate you, the happier your cat will be.
