Oh, Kim, some of those kitties you said goodbye to have been with you a long time. I think you're very wise, and very brave to make such a hard decision. You have to take care of yourself, for the sake of your "keepers," and I think it was positively Providential that such a good rescue organization that you know you can trust came along for the others. Everyone here knows what a terrific catmom you are, and how much you've done for so many. Hang in there, and know that you've made it possible for LOTS and LOTS of wonderful cats to have great homes, who might otherwise have lived life on the streets. You're the BEST!!
