Cats need to drink approximately 40-60 ml of water per kilogram of body weight per day. For example, an adult cat weighing 5 kg would need to drink about 200-300 ml of water per day.

Insufficient water intake in cats can lead to dehydration and even kidney disease, so please ensure your cat has access to enough water. If your cat doesn't like to drink water, consider buying wet food specifically for pets or increasing your cat's exercise to encourage water consumption.
