Why Cats With Diabetes Urinate More Frequently
As the animal’s blood sugar levels increase, the body will signal the kidneys that there is excess glucose and eliminate it via the urinary tract. To do this, a diabetic cat has to drink a lot more water, making her pee more. And as the animal’s kidneys attempt to expel all that excess sugar, peeing more leads to being thirsty more and also of course drinking more water. Polydipsia means drinking a lot more water, and polyuria is peeing more.
You could have also overheard your vet say “the cat may be spilling glucose” meaning glucose is found in the cat’s pee. This, in turn, means that the animal’s body is attempting to expel the surplus glucose that is in the animal’s blood.
