Cats are Anarchists.
Have you ever wondered why cats just don't submit? We have two cats that share our house and believe me when I tell you, they have their own life and we have ours. Occasionally throughout the day our lives will cross paths when they are hungry, want love or want to be brushed.
Even though we do have some rules around the house like not jumping on the couch, there is not doubt in my mind that they will be sleeping on the couch within a few days if we stopped paying attention. Sure you can train a cat but I am always reminded that they only do it so that my wife Anabell would stop harassing them.
