My kitties come when I call them...they don't know their individual names yet, but they know the tone I use. They understand the word NO! and Get off the table! Sometimes they acknowledge that I've said no and then just stare at me like I know you told me No, but what are you going to do about it?! All I have to do then is raise the squirt bottle and it's flying kitties off the table. I don't even have to squirt them anymore...they see the bottle and know.."uh oh...Mom really means it this time!"
