My cat used to climb up my jeans until I put the softpaws on him one day. He went to jump up and climb my pants and then the claws just didn't work and he slid down and I just laughed at him and I was waiting for one of those "WOOOOooooooom" sounds like in the cartoons.

I don't use softpaws on him anymore, but I do keep his nails trimmed regularly now that he's grown up. The softpaws seemed to teach him that "that's not a good idea since it dun work anymore" and we kept them on for a couple months (replacing the ones that fell off).
