When kittens are first born their eyes are closed, their ears are folded, they can't keep themselves warm or eliminate waste. They fit in the palm of your hand and weigh 3-5 ounces. Even though they are helpless, they can purr and make distress calls. They will spend 90% of their time sleeping and the other 10 percent eating. Kittens are completely dependent on their mother for protection, warmth and nutrition.
