I suggest looking for a mature cat; it will be less trouble than a kitten, and its personality will be fully developed. Even a kitty 7-10 years old has plenty of good years left.

Ragdolls (as their name implies) are extremely "laid-back," docile, non-aggressive cats. They tend to relax when held. They are said to possess a non-fighting instinct, which means that if attacked, they do not defend themselves. Because Ragdolls lack the instinct to defend themselves when attacked, they must be kept as indoor pets only. However, they can be easily leash trained so that they can go for walks with you outside. They are very "people" oriented and love to be around others, which often finds them greeting guests and/or following their owners around in a fashion similar to a puppy. They are often quite an attraction in a show ring because of their docile dispositions and acceptance of the judge placing them on their backs, holding them like a baby.
