Cats and kittens can be great companions for children, but younger kids need supervision and guidance for interactions to be positive.  Here are some things to keep in mind:

• A cat's back end should always be supported when she is being carried.
• It is important to let the cat approach the child, rather than vice versa.  Some cats are scared or intimidated by small children.
• Never try to force the interaction and never try to hold a cat that does not want to be held. This will very often lead to a scratch or bite.
• Most cats don't like to be bothered while they are eating.
• Remember to play with toys that keep the cat at a distance from you.  Children often are not able to tell when the cat is about to go after their fingers or toes so it's better to keep the cat at a safe distance.
• Never try to pull or pick up a cat by her tail, legs, head, or ears.
• You should always have a place where the cat can get away from the child (or dog, or adult, or vacuum, or whatever).  This could be a room, a high perch, the basement, etc.  A cat will feel much more secure knowing that she has a safe haven.
• Often the best type of cat for a young child is a large, 2-3 year old neutered male.  This type of cat is often more mellow, tolerant, and durable (better able to withstand an active young child).
• Very small kittens are generally too frail to be appropriate companions for toddlers and younger kids.  Kittens may be a better choice for older children who understand how delicate they can be.  Remember, there is no telling what cat personality a kitten will grow up to have!
• As with any other pet, no matter how tolerant the cat is, never leave a small child unattended with a cat.
