Sorry Black Kitty, Cats can be trained as to where they have to go for the toilet, where they have to eat, not to climb on the furniture, which rooms they are allowed to go into, and all the social skills which make them acceptable in our homes. In these skills they are so much easier than dogs. Admittedly it's impossible to get them to SIT or LIE to command but doesn't mean they are untrainable. You keep a cat. Think about it.
