A kitten is a young domestic cat, typically less than one year old. Kittens are known for their playful behavior, curiosity, and rapid growth. They are born blind and deaf, relying on their mother for warmth and nourishment. As they grow, they develop their senses and begin to explore their surroundings. Kittens usually start to eat solid food around four weeks of age and are weaned by eight to ten weeks. They are social animals and often enjoy interacting with humans and other pets. Proper care, including vaccinations and spaying or neutering, is essential for their health and well-being.
