So glad you were able to make it back to his regular dr. I think it does help when the Vet really knows "who" the cat/dog is. It is just another bond and important part of an animal's life. And it is so difficult to describe those who have managed to crawl into our "hearts". We can love all our animals but there are those whose spirits' vibrations just seem most in tune with ours. May your memories of Felix warm your heart for ever.
