Cat Water Intake Calculator

Cats evolved from desert-dwelling ancestors and naturally have a low thirst drive. In the wild, cats get most of their water from prey (which is ~70% water). A cat eating dry kibble (only ~10% moisture) may not drink enough to compensate, putting them at risk for chronic dehydration and kidney disease — the leading cause of death in older cats. This is why many veterinarians recommend incorporating wet food into a cat's diet.

The easiest at-home test is the skin tent test: gently pinch the skin between your cat's shoulder blades, pull it up slightly, and release. In a well-hydrated cat, the skin should snap back immediately. Other signs include: dry or sticky gums, sunken eyes, lethargy, decreased appetite. If your cat shows multiple signs, offer fresh water and wet food immediately and call your vet.

Try these tips: use a cat water fountain (cats prefer moving water), place water bowls AWAY from food and litter boxes, use wide shallow bowls (cats don't like their whiskers touching the sides), flavor the water with a splash of tuna juice or low-sodium broth, and ensure fresh water daily. Most importantly, feed wet/canned food to increase moisture intake.
