This morning when we awoke, Ratatooey was no longer with us. Sadly, he didn't make it through the night. It was completely heart wrenching to see his little cold, grayish-blue body. It was a bit traumatic, but we were able to bury him in a field, so he could be at peace and roam forever free. I've tried to take comfort in the fact that he was able to rest comfortably in a warm place, being fed, and not ate by ants, but it's difficult to lose something that I'd started becoming attached to so quickly. Regardless, we did the best we could to make his final days comfortable, and perhaps, as Sam said, it was the circle of life.
Rest in peace, little guy.
