Expert Tip
Cats are inefficient drinkers and have a low thirst drive. A cat eating exclusively wet food gets about 70-80% of their daily water needs from their meals.
Calculation Methodology & Details
Formula
Calculates baseline needs using a 50 mL/kg benchmark. Adjusts target water ingestion based on food moisture: dry kibble (95% to drink), wet food (30% to drink), mixed (65% to drink).
