They are 20$ for a pack of 40 you use 10 I used 8 I didn't put one on her dew claw or back paws... They come in all colours and they do work. Only use them if your cat is an indoor cat though. You may think its expensive, but your cat will be better off then being declawed. If you do get them your cat will not even notice them. Pixie still tried to pick the furniture LOL... I don't use them anymore because she eventually stopped doing it. If she does it again I have more to put on her
