The cats - Zane, Harley, Jazz and Cubby - have their own tree. I took the photo in the library, but, it will be set up in the bedroom. I use miniature ornaments and look for anything with a mouse or bird. That includes Snoopy with his friend Woodstock. I have always collected Santas, angels and snowmen, so the tiny versions of those will find their way to this tree also. The string of lights is battery-operated LED.
