PetSafe Drinkwell Platinum Fountain Review: Does Flowing Water Make Cats Drink More?

Quick verdict: The PetSafe Drinkwell Platinum is a well-designed cat water fountain that genuinely encourages increased water intake through flowing, filtered water. After 30 days of testing in a three-cat household, two of our three cats increased their daily water consumption noticeably, and all three used the fountain regularly. The quiet pump, adjustable flow, and dishwasher-safe parts make daily maintenance manageable. It requires consistent filter changes and pump cleaning, but the health benefits of better hydration — particularly for urinary and kidney health — make this a worthwhile investment. We rate it 4.4 out of 5.

Why We Tested the PetSafe Drinkwell Platinum

Chronic dehydration is one of the most common and underrecognized health issues in domestic cats. Cats evolved as desert animals — their wild ancestors obtained most of their moisture from prey, not from standing water. Domestic cats fed primarily dry food are particularly vulnerable to inadequate water intake, which contributes to urinary crystals, urinary tract infections, kidney disease, and constipation.

The Cornell Feline Health Center identifies inadequate hydration as a contributing factor in Feline Lower Urinary Tract Disease (FLUTD), one of the most common reasons for veterinary visits in cats. Anything that encourages a cat to drink more water is, from a veterinary perspective, a meaningful health intervention.

Cat water fountains work on a simple premise: many cats instinctively prefer running water over still water. In the wild, flowing water is generally fresher and less likely to harbor pathogens than stagnant pools. This instinct persists in domestic cats — you have probably noticed your cat drinking from a dripping faucet or showing interest in running bath water while ignoring the perfectly clean water bowl beside their food.

The PetSafe Drinkwell Platinum is one of the best-selling cat water fountains on the market, with a large 168-ounce capacity, a free-falling stream, activated carbon filtration, and a submersible pump. We tested it for 30 days with three indoor cats to evaluate whether the fountain actually increases water intake, how easy it is to maintain, and whether the pump stays quiet over extended use.

Water Flow and Cat Engagement

The Drinkwell Platinum features a free-falling stream that drops from a raised spout into the bowl below. The flow rate is adjustable via a dial on the pump — you can set it from a gentle trickle to a more vigorous stream depending on your cat’s preference.

In our testing, the medium flow setting attracted the most consistent engagement from all three cats. The Siamese mix was fascinated by the falling stream from day one and spent several minutes watching it before drinking. The domestic shorthair was initially cautious — he approached, sniffed, watched the water for about 30 seconds, and backed away. By day three, he was drinking from the fountain regularly. The Maine Coon mix drank from it immediately without hesitation (Maine Coons are famously water-curious).

The flow adjustability is a genuinely useful feature. Some cats prefer a strong stream with visible movement, while others are intimidated by splashing water. Starting with a low flow and gradually increasing it over a few days is a good strategy for cautious cats.

By the end of the 30-day test, the fountain was the primary water source for all three cats. We kept a traditional still water bowl available throughout the test, and while cats occasionally drank from it (particularly the domestic shorthair), the fountain received significantly more use. We estimated a 20-30% increase in total water intake for the two cats that clearly preferred the fountain, based on monitoring the fountain water level and the still bowl consumption over comparable periods.

The health implications of this increase are significant. For indoor cats fed dry food, even a modest increase in daily water intake can help dilute urine, reduce crystal formation, and support kidney function. The AAFP recommends providing multiple water sources and considering a fountain as part of a cat-friendly home environment.

Filtration and Water Quality

The Drinkwell Platinum uses replaceable activated carbon filters that sit in the flow path. The carbon absorbs organic compounds, odors, and off-tastes from tap water, providing cleaner, more palatable water to your cats. The filter also catches loose debris — hair, food particles, dust — before it reaches the pump.

In practice, the filtration makes a noticeable difference in water freshness. We compared the taste and smell of fountain water versus the same tap water sitting in a still bowl after 24 hours. The fountain water remained odor-free and clean-tasting, while the still bowl water had developed the slightly stale quality that standing water develops at room temperature. This difference is likely perceptible to cats, whose sense of taste and smell is far more acute than ours.

Filter replacement is the primary ongoing cost of fountain ownership. PetSafe recommends replacing filters every 2-4 weeks. In our three-cat household, we found that filters showed visible discoloration and reduced water clarity by the 2-3 week mark. A 12-pack of replacement filters costs approximately $15-20, which breaks down to roughly $1.50 per filter — a modest ongoing cost.

Running the fountain without a filter is technically possible, but we do not recommend it. Without the carbon filter, the water will develop off-tastes more quickly, and debris will accumulate in the pump, reducing its lifespan and increasing maintenance frequency.

Noise Level and Pump Performance

The submersible pump is genuinely quiet — during normal operation with adequate water level, the only sound is the gentle splash of the free-falling stream hitting the bowl surface. This is a pleasant, natural sound that most cats find attractive and most humans find unobtrusive. We measured the sound level at approximately 25-30 dB from three feet away — quieter than a whisper.

Noise becomes a concern only when maintenance is overdue. Two scenarios cause audible pump noise:

1. Low water level: When the water drops below the minimum fill line, the pump intake begins pulling air along with water, creating a buzzing or gurgling sound. This is easily resolved by refilling the fountain. With the 168-ounce capacity, refills are needed approximately every 2-3 days in a three-cat household.

2. Mineral buildup on the impeller: Over weeks of use, mineral deposits from hard water accumulate on the pump’s impeller (the small rotating component that moves water). This causes the pump to vibrate against its housing, producing a humming sound. Cleaning the impeller with a small brush and white vinegar every two weeks prevents this.

Over our 30-day test, the pump ran continuously without failure or significant performance degradation. We cleaned the pump at day 14 and found light mineral deposits that took about three minutes to remove. Post-cleaning, the pump returned to its original silence.

Value Assessment

The PetSafe Drinkwell Platinum is priced in the mid-range of the cat water fountain market:

• Budget fountains (Catit Flower, basic models): $20-30
• PetSafe Drinkwell Platinum (this product): $35-50
• Premium fountains (PetSafe Ceramic, Drinkwell Pagoda): $60-80
• Stainless steel fountains (Pioneer Pet, Veken): $30-50

The ongoing cost of filter replacements adds approximately $6-10 per month depending on replacement frequency and whether you buy in bulk. Over a year, the total cost of ownership (fountain + filters) is approximately $100-170.

Is this worth it? Consider the alternative costs:

• A single veterinary visit for a urinary tract issue: $200-500
• Treatment for urinary crystals or blockage: $500-3,000+
• Prescription urinary health diet: $40-60/month ongoing
• Chronic kidney disease management: $100-300/month

Investing $100-170 per year in a tool that meaningfully increases water intake — and thereby reduces the risk of these expensive, painful conditions — is one of the most cost-effective preventive health measures available for indoor cats.

Who It Is For

Buy the PetSafe Drinkwell Platinum if:

• Your cat prefers running water — drinking from faucets, showing interest in flowing water
• Your veterinarian has recommended increasing your cat’s water intake for urinary or kidney health
• You feed primarily dry food and want to offset the low moisture content with increased water consumption
• You have multiple cats and need a high-capacity fountain that does not need daily refilling
• You want dishwasher-safe parts for easy thorough cleaning
• Your cat has a history of urinary tract issues, crystals, or early-stage kidney disease
• You are willing to commit to the bi-weekly maintenance routine of filter changes and pump cleaning

Skip the PetSafe Drinkwell Platinum if:

• Your cat is frightened by flowing water and shows no interest after a gradual introduction period
• You want a maintenance-free water solution — fountains require more care than a simple bowl
• You are concerned about plastic and prefer stainless steel or ceramic for bacterial resistance
• Your cat already drinks adequate water from a still bowl and your vet has no hydration concerns
• You travel frequently and cannot maintain the bi-weekly cleaning schedule

For additional guidance on supporting your cat’s hydration, the AAFP’s water recommendations provide excellent advice on water placement, temperature, and bowl type preferences. Combining a fountain with a high-quality diet that includes some wet food — see our Blue Buffalo Tastefuls Indoor review or Purina Pro Plan Indoor review — provides the best overall hydration strategy for indoor cats.

Final Verdict

The PetSafe Drinkwell Platinum earns a 4.4 out of 5 from Meowing Goods. It is a well-engineered fountain that delivers on its core promise: encouraging cats to drink more water through flowing, filtered, clean water. The 168-ounce capacity, quiet pump, adjustable flow, and dishwasher-safe parts make it one of the most practical and low-maintenance fountains in the mid-price range.

The maintenance commitment is real — you need to change filters every 2-4 weeks and clean the pump biweekly — but it takes less than 10 minutes and becomes routine quickly. The health benefits of increased water intake for indoor cats are well-documented, and a fountain is one of the most effective tools for achieving that goal. If your cat shows any preference for running water, the Drinkwell Platinum is a sound investment in their long-term urinary and kidney health.

Frequently Asked Questions

Do cat water fountains actually make cats drink more?

Multiple studies and veterinary observations support the finding that many cats prefer running water over still water and will increase their daily intake when provided with a fountain. In our 30-day test, two of three cats showed a measurable increase in water consumption — one by an estimated 20-30%. The Cornell Feline Health Center notes that adequate hydration is critical for urinary tract health and kidney function.

How often should I change the filter in the PetSafe Drinkwell?

PetSafe recommends replacing the activated carbon filter every 2-4 weeks. In our testing with three cats, we found the filter lost effectiveness around the 3-week mark. We recommend a 2-week cycle for multi-cat households and a 3-4 week cycle for single-cat households. Replacement filters are available in bulk packs.

Is the PetSafe Drinkwell Platinum noisy?

The submersible pump is remarkably quiet during normal operation — approximately 25-30 dB from three feet away. The only notable sound is the gentle trickling of the water stream. Noise increases when the water level drops too low or when mineral deposits build up on the pump impeller. Keeping the water level above the minimum line and cleaning the pump every two weeks prevents noise issues.

How do I clean the PetSafe Drinkwell Platinum fountain?

Disassemble the fountain and place the bowl, ramp, and reservoir on the top rack of the dishwasher. Clean the pump by hand using a small brush and white vinegar to remove mineral deposits from the impeller. Rinse all parts thoroughly before reassembling with a fresh filter. A full cleaning takes about 10 minutes and should be done every 1-2 weeks.

Should I get a plastic, ceramic, or stainless steel fountain?

BPA-free plastic fountains like the Drinkwell Platinum are the most affordable and practical, but plastic can develop micro-scratches that harbor bacteria over time. Stainless steel is more hygienic and resistant to scratching. Ceramic is attractive but fragile. Start with plastic; upgrade to stainless steel if your cat develops chin acne or if you prefer maximum hygiene.
