Clarifying queries to pose to oneself Does your cat eat wet food? Has their drinking behavior recently changed? Do you have any diarrhea, vomiting, or lethargy?

Recommended daily intake and how to calculate it

Daily Water Intake for Cats How Much Is Enough

As a general guideline for daily water needs, many veterinarians recommend 4 ounces per 5 pounds of body weight (about 0.88 fl oz per pound); however, this varies depending on nutrition and personal circumstances.

Compared to cats fed solely dry kibble, cats fed wet food will require less free drinking because they get a large amount of their fluids from food. If you’re keeping an eye on a health condition, you should always measure. To determine a goal volume, weigh your cat and multiply the result by the per-pound guideline.

Does Wet Food Reduce a Cat’s Water Needs

Yes—in a big way.

Food that is wet: 70–80% moisture

Food that is dry: about 10% moisture

Since they acquire their hydration from meals, cats who eat predominantly wet food frequently drink relatively little from their water bowl. For appropriate hydration, cats fed dry food must consume more water.

Chekapaws Advice: Be especially mindful of your cat’s water consumption if they only eat dry food.
