Hi,
I just wanted to say I'm sorry you and your baby are going through this.
One of my boys is in kidney failure too so I know how you feel. It's a horrible disease. Bear takes Azodyl too and is on sub q fluids and Zantac for nausea. If you haven't started your boy on fluids yet, that may be something you want to talk to your vet about. They should be able to teach how to do it at home yourself. My boy wouldn't eat the low protein diet either so I feed him whatever he wants. One day he will eat one food really well and the next day he doesn't want any part of it so I have to try something else. I keep several different kinds in the house to give him a variety. Good luck to you and your baby. I hope he's feeling better soon.
