Are you able to tell how much water he drinks daily? I mean, do you have a bowl for water, or does he drink from taps, fountains, else? In the case of a bowl, you could weigh it when you fill it with fresh water, and weigh again before emptying it to refill it.I've noticed my cat has had a big increase in water intake and urination. I was told that could happen a bit with Plavix, but this feels like a lot. Anybody have any thoughts? I'm gonna give my vet a call tomorrow because wow, this is getting to be a good bit of pee.
I used to do this when my cat was sick and I thought she was drinking a lot. She was on a diuretic too. What I noticed, though, was that the diuretic was sort of dehydrating her. Despite the whole amount of water she would drink, the moisture of the wet food and the sub-Q's I was giving her, her hydration was poor due to the massive urination.
Are you also able to tell if your cat is hydrated? Skin test on the back?
