If you just got a new kitten, you probably know that cats are nocturnal animals. Their night time antics can keep you up at night. In the interest of your own sanity as well as your kittens health and safety, set the ground rules early on.  If you allow your kitten to sleep in your bed overnight, you may be setting a precedent that you may later regret. Make his own cat bed instead.  Place it somewhere quiet, warm and cozy. If kitty continues to climb out of his bed and into yours, you may want to keep him in a separate room at night. Remember, your pets count!
