Filou is on fluids now since April 2005. He's doing very well.
He gets weekly fluids but of course the amount and frequency depends on the state of the kidneys- so it will be more often later

In the case of Cosmo it was kind of a kidney crisis, so they will start with IV fluids- as opposite to the Sub-q fluids that you can administer yourself.

Many kitties here have become better after such a crisis and I am sure Cosmo will have quite some happy time with you.

One thing about kidney transplant: If you transplant a kidney in humans then in many cases it is a donor who knows about it and has agreed. In the case of cats the kidney is taken from another kitty who has no chance to agree to anything.... I would never do that. It is a risky operation and it is not sure that my cat would live that much longer and with much better life quality. Filou is only ten years old and when he has to go it will break my heart- but I will not put two kitties under the stress of a kidney transplant.
