A baby cat is called a kitten. Kittens are born blind, deaf, and vulnerable, relying entirely on their mother for warmth and nourishment in their early days. Their eyes typically open around one to two weeks old, and their playful and curious nature often begins to emerge shortly after. As kittens grow, they develop social skills, learn to explore their surroundings, and engage in play to develop hunting instincts. The developmental stage of a kitten extends from birth to around six months, during which they transition from helpless infants to independent young cats capable of living on their own.
