Why Is My Kitten Dragging His Back Legs?

Why does my kitten drag his back legs?

why do kittens have to be declawed?

My female cat is 7 years old, and she has a habit of dragging her rear legs. Why would she do that? Is it normal for cats to drag their hind quarters after they are neutered or spayed? What can I do about this behavior without causing pain or injury to my kitty? Please help!! -Penny
