A ship is safe in the harbor, but that is not what a ship is for....

I feel such pain for you in both your loss and your search for an answer to that loss. There is no way to make our lives or the lives of our pets totally without risk. Nor do I believe such a life would be worth living. You took such great effort for their quality of life -- the raw diet, etc!

The times they felt the wind ruffle their fur, smelled the grass and the trees and the birds and the mice -- only enhanced their lives.

It was fate....very, very very sad fate.
