Lots of Prayers for Fluffy and you too. My Mishi is a kidney cat too and there have been times when I had to give him SubQ fluids twice a day. Kidney cats do tend to protein waste and get very thin. I had no problems giving him the fluids and he was SO good in letting me, but then the big goon just loves me and will let me do almost anything (except clip his claws ) You do get used to it. Think of it as extra special time with your kitty and just treasure the moments you have together.
