Prayers going out to you and Filou (and Tigris and Siegmar) that the going gets easier. I'm dealing with Mishi's kidney disease too right now so I KNOW exactly what you're going through. Do have your vet show you how to give subcutaneous fluids yourself - it's not difficult and I know Mishi is much more comfortable having me do it than taking him in to have the vets do it.

C'mon Filou - All the PT kidney kats have to stick together and stay on this side of the RB for a bit longer. Their PT guardians need you here!
