Go read about Kozmo on Tiff's blog, if you want to see his sweet eulogy. He was a sweet ducky and will be missed.
She has a little memorial fund that will go to fund the rescue and rehoming of other abandoned waterfowl. If you are needing some good karma for the day, consider PayPal-ing over a couple bucks. As Tiff says, "it's for a good Koz."
