kittens
They know what “no” means and are learning that they can’t jump up on the counters or kitchen table, although I am not sure what they do when I am not in the room. I have a squirt bottle that has worked quite well in keeping them from clawing the couch. Some one suggested that.
They don’t know what hit them and they dash away in a flash. It is a comfort though, to have a warm kitty sleeping on your lap.
