How to Get Your Cat to Drink More Water — Keep Your Feline Healthy & Hydrated
What Makes Petfairs the Smart Sourcing Choice?
Why hydration matters (quick facts you can trust)
- The average healthy cat needs about 4 ounces of water per 5 pounds of body weight per day — so a 10-lb cat drinks roughly 1 cup daily (wet food reduces that need). This guideline comes from Cornell University’s Feline Health Center.
- The U.S. pet market is large and growing — millions of American households own pets, so hydration products (fountains, automatic feeders) are fast-moving retail items. The American Pet Products Association (APPA) reports ~94 million U.S. households own at least one pet and projects $157 billion in industry sales for 2025 — useful context if you’re a store thinking about stocking hydration gear.
How much water should a cat drink a day?
How long can cats go without water — and why you shouldn’t test it
How long can a cat go without food and water?
- Without water: dehydration becomes life-threatening in about 24–72 hours depending on the cat’s health and temperature.
- Without food (but with water): cats may survive longer—sometimes several days to a week—but refusal to eat for 24–48 hours is a red flag. Prolonged fasting can trigger hepatic lipidosis (fatty liver), a life-threatening condition in cats. PetMD and Purina advise prompt veterinary attention if a cat refuses food for more than a day.
Practical, tested ways to get your cat to drink more water
Use a cat water fountain (running water wins)
- Results (Abstract): The average water consumption rate from flowing water sources (115.44 mL) was higher than that from still water sources (109.83 mL), but this difference was not statistically significant. The study found that individual cats had strong preferences for one type of water source, but no group preference was established.
Offer multiple shallow bowls
- Results (Abstract): Overall, the type of water bowl had no significant effect on water intake. However, three individual cats showed significant drinking preferences (one preferred the still bowl, one the circulating bowl, and one the free-falling bowl).
- At Petfairs, we recognize and cater to this variability by offering a diverse range of options—from smart feeders with integrated water functions to water bowls in various materials (ceramic, stainless steel, and more). This ensures that every cat owner can find a solution perfectly suited to their feline companion’s unique preferences, making it easier to encourage consistent hydration.
Add water or low-sodium broth to meals
Switch some meals to wet food (or mix wet + dry)
Keep the water fresh (change it daily)
Try different temperatures and bowl types
Make hydration fun
Vet signs to watch — when to call for help
- Little to no urination or very dark urine
- Sunken eyes, dry sticky gums, lethargy
- Loss of appetite for more than 24 hours Veterinary centers can provide subcutaneous fluids (at home or in clinic) to correct dehydration — don’t wait until the situation worsens.

Effects of Flowing Water Fountains on Cats’ Water Intake
- Purpose: Evaluate whether using a bowl or a fountain increases cats’ water intake and dilutes urine.
- Results (Abstract): After excluding one cat that showed stress responses to the fountain, the remaining 12 cats consumed slightly more water from the fountain than from the bowl. However, there were no statistically significant differences in water intake or urine osmolality (a key indicator of concentration).
- Conclusion: In this study, fountains failed to significantly increase cats’ water intake or dilute urine. The researchers suggested larger-scale, longer-duration studies to clarify the results.
