Cats are naturally intelligent, active by nature, like to play, and have strong curiosity. They show great interest in insects, yarn balls, ropes, paper balls, and leaves blown by the wind, often fiddling and playing with these things. Usually, under the owner's coaxing, cats can instinctively perform various interesting actions such as rolling over, lying on their back with limbs up, and standing upright.

　　However, training cats to perform more complex actions is much harder than dogs. This is because cats have a strong sense of independence and an extremely stubborn character, unwilling to be controlled. Cats will insist on doing what they like even if the owner forbids it, and often refuse to do what they dislike even when forced. Additionally, cats are naturally vigilant and tend to become frightened by strong light and large crowds, making it difficult to perform publicly.

　　Nevertheless, with patience and scientific methods, cats can be trained and disciplined well in a relatively short time.

　　All cat behaviors are based physiologically on neural reflexes. Reflex activity refers to the process in which an organism’s receptors receive a certain stimulus and, through the nervous system, cause the organism to react. The occurrence of reflex activity requires a stimulus, which is something that can be perceived by the body’s cells and triggers a response. These are changing internal and external environmental factors, such as tapping, pressing, light, sound, temperature, etc. Cats have various sensitive receptors, including visual, auditory, olfactory, and skin-based receptors for temperature, pain, and touch. These receptors perceive different stimuli separately and convert them into nerve excitation processes. When the excitation travels along afferent nerves to the brain, the brain immediately responds and sends commands via efferent nerves to effectors (muscles, glands, etc.), prompting them to perform corresponding actions.

　　Animal reflexes can be divided into two main types: unconditioned reflexes and conditioned reflexes. Unconditioned reflexes are innate, present from birth, and are the most basic and important reflex activities for animal survival. For example, kittens naturally know how to nurse and breathe after birth. Stimuli that trigger unconditioned reflexes are called unconditioned stimuli, such as food, touch, and tapping. Conditioned reflexes are those developed after birth as the animal adapts to its environment during life. These acquired reflexes ensure the body maintains a high level of balance with its surroundings and include habits formed during care and various abilities cultivated through training. These reflexes are unique to the individual animal.
