Training Cats Starts from Young
Siamese
Everyone knows that cats are not like dogs and cannot accept strict obedience training. Cats are naturally aloof, quite clever and practical. Historically, the ancestors of cats lived a loner lifestyle and knew well how to protect themselves. Also, cats have a strong sense of pride, making it difficult to demand they obey human will. Usually, cats are willing to be controlled by people only when they see it benefits themselves. For example, when they are hungry or feel cold, they will make demands and obey certain commands.
But you should understand, many times when a cat lies in its owner's arms, it is a voluntary behavior and not because it obeys you. When it rubs its head and body against the owner and makes soft meowing sounds, it is only because it is hungry, wants food, or has some other demands that humans may not understand.
Of course, it is not that cats cannot be trained at all. Cats are very smart and can learn many actions and behaviors. If training starts when the kitten is five to six months old, some results can be achieved. For example, cats can be trained to open doors, stretch paws, roll over, carry objects, and use a fixed place to relieve themselves. Kittens are more dependent and more adaptable during this period, so training should be intensified to form habits. Otherwise, once the cat matures at one year old and their personality develops, they will no longer willingly obey human training. (Source:PetsZone)
