Cat Water Intake Calculator

Estimate your cat's daily water needs based on body weight. Water requirements may vary depending on diet, activity level, age, environment, and health conditions.



Daily Water Requirements

Most healthy cats require approximately 50 to 60 milliliters of water per kilogram of body weight each day. This calculator uses 55 ml per kilogram as a general estimate.

Why Hydration Is Important

Proper hydration supports kidney function, digestion, temperature regulation, and overall health. Cats that primarily eat dry food may require additional water intake.

Signs of Dehydration in Cats

Common signs of dehydration include lethargy, dry gums, reduced appetite, sunken eyes, and decreased skin elasticity. If you suspect dehydration, contact your veterinarian.
