Thank you for your reply. This is so new to me! I've been doing a lot of research on the internet too. Bailey drinks differently than our other cat. Tatiana drinks off and on throughout the day, little bits at a time, kind of how she eats. Bailey, on the other hand, will drink a lot all at once, then not for awhile. She does drink every day though. Maybe I"ll have to look into the fountains.

I spoke with someone that sells Holistic foods, where I buy theirs. She did say to get the vet's food for now, in order to clear up the current problem, and then possibly look into another brand if I want to. She did make sense.

At least both cats like the Royal Canin so far!
