From what I hear, they DO work, but it gets expensive after a while. You litterally glue the soft paws on like you would a fake nail on yourself. When one falls off, you reapply.

Have you tried regular trimming of her nails? A kitten that old should need weekly trims to keep her from scratching things up. I know mine scratch a whole lot less when their nails are neat and trim. (My youngest are almost 5 months old and I trim weekly - sometimes I swear they need it daily! I even trim Pouncer's nails weekly, and h's a year and a half.)
