@BillRM,
Bill, I understand your thought about adopting a new kitten to replace your loss. When my dogs and cats had to have their suffering ended, I immediately replaced them, especially if they they were couples and one of them remained. It help to overcome the loss of their partner, and it certainly helped me to reduce my sorrow. I think Blue Eyes would want you to have a new kitten to love. What ever works for you will be the best.
