Thanks so much, guys!
I will keep an eye on her. Her last toys were stuffed ones and before that was a Kong, but that was a while back...she may not be used to this type of toy. I am actually amazed that it is still in one piece.
By the way, I am realllllllly overprotective with her. Always have been, but when our cat died in June, it was so sudden (a clot) and I could not have controlled it, but I blamed myself. So, now Sophie is the only child and must deal with my obsessing.
