Pet Water Intake Calculator
Normal daily water for a dog or cat by weight — and the change that signals a vet visit.
Wet food supplies much of a cat's intake, so a wet-fed cat drinks little from the bowl and that's normal. The clinically useful signal is *change*: sustained intake above ~100 ml/kg/day (polydipsia) is a classic early flag for kidney disease, diabetes or thyroid problems — measure the bowl for a few days before the vet visit, that data is genuinely valuable.
