How much drinking is normal for cats?

[CatDad]

I agree with Jen, there is not a real normal for cats. However, I would also look for a change. I don't know about the UTI food, but that may be the reason and you have nothing to worry about.

My Flicka had kidney diseases and if you are worried get her checked, but I would also wait for a scheduled visit. Unless you notice a drastic change, of course. We had Flicka checked when she started to pee in the wrong places.

Please let me know if you find out.

Tubby & Peanut's Mom if you have any questions on kidney failure please let me know. I am no doctor, but I did go through alot and may have a few insights. Just thought that I would offer.

EDIT:
Cool, I stand corrected. I should have know that someone had studied this. Thank you Cinder & Smoke.
