I am so sorry for your loss.
I don't have anything I can say other than there is a plan out of our hands with this. We lost a boy cat in '08 of renal too, & it came so fast that even though we noticed his over-drinking wasn't normal, we had no idea we'd take him to vet & told he need sub-q fluids & it may only help a few days. He was put to sle
ep a few days later.
I really hear you story & know this is not even real nor fair to you. Please accept my sincerest wish that you stay strong til you WILL see your kitty again at Rainbow Bridge. Please take care of yourself, & do know many here support the feeling of shock & trauma you're going to deal with for a long while. I am sad along with you just knowing his occurred yet again to a kitty out there. Thank you for sharing her life story with us.
