Okay, first off, your mother is completely wrong. Dialysis is a totally different process than Intravenous fluids. And many cats with kidney problems can live long, active lives with the right care. You can learn to give Honey IV fluids at home if you are not squeamish about needles, and that can save you a trip to the vet every couple weeks. Ask for one more visit, and I am sure they would be happy to show you how and what to do.

Dialysis is a whole different thing, I'll describe that in a bit. Just wanted to post this quickly.
