Oh, Randi, I am so very very sorry. My heart breaks for you and Fister both. So much love you share.
Prayers for dearest Fister for a miracle, prayers for him to come home and you both have some more good time together before you say goodbye.
Hugs to you, gentle pets to Fister, and love to you both.
I've been Frosted (thanks, Elyse and Karen!).
