I'm with KarenI. Maybe I'm a big softee, but I would probably cry and feel guilty for days if the pepper got in their eyes. I did try the spray. It didn't work, and ammonia makes me sneeze, so I don't want to be around that smell. I guess my boys are spoiled rotten. It's funny, I've been called "dragon lady" at work but at home I'm a wimp I just put the trash out of their way. Maybe I'll give the mustard a try.
