Your Cat’s Nutritional Requirements: The Basics

Water.Because cats are designed to fulfill most of their water requirements by eating fresh raw food, they naturally have a low thirst drive. This can lead to health issues for cats that eat dry cat food products and treats. One of the problems is that even though they become dehydrated eating the kibble, their natural "programming" may not encourage them to drink more water. And their urine can become too concentrated. Even though a healthy cat doesn't drink much, you should always have clean good quality drinking water available to them. And please make sure it's good quality water, which means tap water may be out, especially if your community puts fluoride and chlorine in the water supply. If you have well water, have it tested annually for contaminants.

Not good enough for cats and dogs but we can drink it.
