Cats and humans share many personality similarities. If you raise a cat from kittenhood, you'll find that there's a mutual influence between you and your cat. For example, before getting a cat, you might have been an irritable and impatient person; but after getting a cat, over time, you'll find your emotions gradually stabilize. This is the effect of having a cat—your personality is influenced by your cat.
Similarly, if a cat is naturally quiet, while its owner is overly active and lively, the cat's normal life will inevitably be affected. The cat will gradually become more like its owner, becoming more active, mischievous, and energetic.
