They are also full of mischief and can get into everything you own. They can destroy plants, and they love to play on top of you during the night. As with any babies, they take more time than adults. That said, they really are charming and fun. Simply put your breakables out of the way during the first year.
Cats quickly become very graceful, and can learn to avoid sending things flying.
If you plan to get a kitten, consider getting two. They keep each other great company and provide themselves and you with a lot of entertainment. They re actually less trouble in pairs, as they take out their wild kitten energy on each other rather than on your hands and clothing. Adult cats are a very good idea for many people. They re still playful, but not as wild as kittens.
