The common term for a baby cat is "kitten." Kittens are born blind and deaf, relying on their mother for warmth and nourishment. They begin to open their eyes and start walking at around two weeks old. Kittens are known for their playful behavior and curiosity, which are important for their development. They typically stay with their mother for several weeks, during which they learn important social behaviors and skills. After several months, they can be adopted into new homes, where they often continue to exhibit the playful and affectionate traits associated with felines.
