Cats often drink less, especially on wet food. A fountain is an experiment. A sudden change in drinking or weeing is a vet call, not a shop call.

How it will decide

50 ml per kg per day is a commonly quoted starting figure for healthy dogs, including moisture in food.
It is not a prescription and not a reason to restrict or force water.
Cats are not given a millilitre target. A sudden change is a vet question.

Is this veterinary advice?

No. WellPawed tools are practical checklists. They do not diagnose, prescribe or say that a walk or a product is safe.
