I am so sorry Lonnie! To end the suffering by your amazing love for Zippy. You must not suffer but know you did a very humane thing. What a blessing that you had him for the time you did and especially that Zippy had you. The Lord created him and blessed you with him, what a gift and a mercy. All beginning and ends are His and you have a memory that is priceless. My husband brought me to an animal shelter the day after my Milo died suddenly, I thought it cruel at first, I didn't want another cat, I wanted Milo, but when I walked into the shelter, (never been to one) there where a whole lot of helpless hopeless eyes looking at me, we took one home it didn't replace Milo but it sure was heart warming to give one of these sweethearts a forever home, in memory of my Milo. We have adopted three more since then, Milo was a huge void to fill but now their is four kittys rescued from shelter. Zippy is not suffering and you did the most loving thing, I feel your pain and I hope you are able to give that love again to a kitty that would adore a love as yours,priceless. Susie
