Kito is a brat! She figured out how to get the "nut" off the bottom. It doesn't matter what goodies I put in it, all she wants to do is take it apart, chew on the "nut" and play with the metal rod. I'm afraid she will hurt herself swinging that heavy metal rod around so I had to take it away. Maybe I can string it on a thick piece of leather, otherwise I'm going to have to get rid of it.
