Cat Water Intake Calculator
Estimate a cat's daily water range from body weight.
—
Formula
Daily water is roughly 40 to 60 ml per kilogram of body weight, with 50 ml per kilogram as a typical midpoint.
How it works
The same weight-based range as for dogs is used, but cats often drink less visibly because wet food contributes fluid. Multiple water points and a running fountain can encourage drinking.
FAQs
My cat barely drinks. Is that normal?
Cats on wet food drink less from a bowl, which is expected.
Do cats prefer running water?
Many do, which is why fountains are popular.
When should I worry?
A sudden change in drinking, either way, is worth checking.
