The baby name of a cat is called a "kitten." Kittens are usually born in litters, with an average of around 3 to 5 kittens per litter, although this can vary. They are born blind and deaf, relying on their mother for warmth and nourishment through her milk. Kittens grow rapidly during their first few weeks of life and begin to explore their environment as they start to open their eyes and ears. The playful nature of kittens makes them popular pets, as they often exhibit curious behaviors and can be quite entertaining to observe as they learn to interact with their surroundings.
