Make sure you have a couple of scratch post at least. They have to scratch...no way around it. When the kitten starts scratching your furniture firmly say "NO" and the move it to the scratch post or the post to the cat. When it scratches the post do the whole "good kitty" thing. One thing to remember, cats are NOT like dogs. They don't really "train" like a dog but will ususually comply if it isn't a problem for THEM. In other words, if you don't have something better for them to scratch...you can say "NO" all you want but they will continue to scratch your furniture.
