If you have a dog and a cat at the same time, you will find that cats are really difficult to train compared with dogs, because cats are aloof, more intelligent and practical. In history, the ancestors of cats have long lived the life of lone swordsmen and know how to protect themselves. And the cat’s self-esteem is strong, it is difficult to ask it to obey people’s will. Usually, cats are willing to be controlled only when they think it is in their own interests. For example, when hungry or cold, cats ask people and obey certain orders. But you should be aware that many times, cats lie in the arms of their owners out of their own volition, not at your command. When it wipes its owner with its head and body, and makes a tender meow, it is only because of hunger, want to eat, or some requirements that people can’t understand. Of course, cats are not totally untreatable. Cats are very intelligent and can learn a lot of actions and behaviors. If the kittens are trained from five to six months old, some results can be achieved. For example, it can train cats to open doors, extend their claws, roll, carry objects and fix them in a certain place to excrete. Kittens are more dependent and more malleable in this period of time, so cats should step up training to form a habit.
