Several studies have shown that cats NEVER make up what they lose at the water dish.They do not have thirst mechanisms like dogs or people do; they only drink AFTER they are dehydrated. That's why they need moisture in their food, no matter how much you see them drinking from their dish.
OMG!!! All those armies of dessicated, dehydrated cats. I guess there must be something different & special about the blood osmolality receptors in a cat's brain (as opposed to a human's) so they ONLY respond to blood glucose and not sodium or anything else. That must be why you see polydipsia in a hyperglycemic cat even though all the other cats just get dessicated when they don't drink...
Usually you have to go to Dr. Hodgkins board to find idiocy of this magnitude. Thank you for bringing it to this one.
That makes no sense. There are many conditions like (diabetes and CKD) that can cause polydipsia in cats, but lack of polydipsia is not proof that the cat is sufficiently hydrated. Humans can easily be chronically dehydrated without exhibiting polydipsia. It has been PROVEN (see studies above, but there are many, many more) that cats lack sufficient thirst drives to fully compensate for the lack of moisture in dry food, and cats eating mainly a dry diet ARE dehydrated, which is why kidney disease and and urinary tract disease are so common in middle aged and older cats. These are facts, not theories. I would recommend
reading the articles on the subject.
To illustrate more plainly, here is a table taken from a
study on UT disease which illustrates the water intake and urine volume in cats fed wet or dry food:
Urine output is
halved in cats on dry diets. Which any medical professional knows is an indication of dehydration.
Unless you've tried this & logged the glucometer readings, you simply don't know. This food is more than just fine for a diabetic cat.
I did log Bandit's glucometer readings on several advertised ultra-low carb dry foods and treats because I was trying to find something I could put in one of those treat balls that wouldn't raise his BG. They ALL raised his blood glucose levels from anywhere from 50-150 points. I've seen cat after cat on these boards eating low carb dry foods with elevated BG, which lowered once the dry was removed, or had to go back on insulin because of the introduction of a low carb food. Yes, a few cats can handle them. But many can't, and in my opinion, it's certainly not worth the risk of losing remission, as well as the increased risk of urinary tract and kidney disease.
My great-grandmother lived to be 101 and smoked cigarettes her whole life, but I wouldn't go around recommending that it's healthy to smoke cigarettes. There are always exceptions to the rule, but that doesn't make the exception the rule.
EDIT: The table didn't save it's formatting, so I entered it as an image instead.
