Hello and thank you for getting back to me. She has not been drinking 10 cups of water, but I did have her drinking significant amounts of water. I have a question for you. Doesn;t too much water damage the kidney? this is the reaseon I have been controlling how much water I give her. SHe had kidney failure 2 years ago and barely made it out alive, now she has one kidney and I'm extremely careful on what I give her. Should I give her ten cups even if she is only 100 pounds?
