Karen's absolutely right. It is NOT dialysis. Intravenous fluids are given sub-Q, which is giving fluids just beneath the skin, to help hydrate them.

Another thing is dry food can put stress on the kidneys, as it's dry. Your cat sounds pretty healthy otherwise. I've been taking my cat Maya Linn to a holistic vet who told me that dry food does put stress on the kidneys and she only feeds her cats canned food.

It can get expensive to bring your kitty into the vet twice a week for sub-Q fluids to be administered. It's not that difficult if you know what you're doing. Maybe your vet can show you how to do it and give you an IV bag of Ringers to take home. It's more scarey than it looks. I was nervous the first time I did it, but it gets earier each time you do it.

I wish you luck. The best thing you could do for your furbaby is to keep him happy, loved and fed.
