And I am not going to get in the middle of that thread. But....why do you believe that animals do not understand what we say to them? I will agree that when I say a long string of words, like "oh you are such a sweet kitty", my cat has no idea what I have said. But when I say "no" or call his name, I get the response that I want---so is he not able to understand that?
I just figured that if you bring it here, I will continue it here.
