There are certain mats you can buy with raised "nubs" on them that are unpleasant feeling for both dogs AND cats, so they won't want to jump up. It seems a little more humane than zapping them. I'll look in my Drs. Foster & Smith catalog, I know they've had tons in there before when I looked through it. It's cheaper, too. Agg, I can't find it. But all it is, is a plastic mat with raised nubs on it that you place on your couch or anything you don't want your pets jumping on (counters, chairs, tables, etc).
