Where's Rookie?

Every time I walk by these empty bowls it reminds me that our cat Rookie has been gone for about a week now.  He just never came home one night.  Even though he was a pretty crazy cat, we're all still pretty sad about it.  I guess I'll have to clean up the kitty food, put the bowls away, and say good bye to Rookie for good.  

Here's Rookie in our Christmas tree.  Yep, he would climb the Christmas tree in the house.
