I am so sorry for your loss. My heart goes out to you and Chico.
My thoughts and prayers are with you.
Miss Kitty, we actually own a rabbit harness and my daughter is training Luna with it. She went to the petstore the other day. We told her that the rabbit is now her financial responsibility, so she has bought more bedding and hay and all that stuf and the harness. It's really funny. I'll have to take pictures of it.
