Question: how many ml of water should a cat drink per day?
Answer: Typical recommendations are that a cat requires about 50 mL of water per kg of bodyweight daily ( 3 ) – so this translates into 200-250 mL per day for a cat weighing 4-5 kg. This water requirement can be covered by the intake of “free water” from liquids and food, or from “oxidation water” produced by metabolism.
