Taz's Tree

I call it Taz's tree.  Ever since she came to live with us, she is fascinated by the hole at the base of this tree.  She is always sniffing and scratching around it.  Today, something new  must have spent some time  in that tiny little cave because when I took Taz for her walk, she dove into the space.  She was not a happy Yorkie as I picked her up and carried her barking away from her tree.  Who knows what was there or had been there.  I did not want to know.
