Where Comfort Meets Care — PetCareShed’s Feline Picks
Introduction — Why Hydration Matters More for Modern Indoor Cats
Hydration is a critical, but often overlooked, element of feline health. Unlike humans, who feel thirsty when dehydrated, cats are naturally poor drinkers. Their desert ancestry allows them to survive on minimal water intake, but modern lifestyles present a different reality. Indoor cats are eating more dry food, living longer lives, and spending more time in temperature-controlled environments — factors that increase their hydration needs.
Many Australian vets regularly see cats suffering from urinary issues, crystals, blockages, and early-stage kidney problems, all of which are heavily influenced by daily water intake. As a result, providing fresh, accessible, and appealing water sources is essential for long-term health. This is where running water — and specifically water fountains — becomes a practical, science-backed solution.
Understanding the Instinct — Why Cats Prefer Running Water
Evolutionary roots from desert-dwelling ancestors
Domestic cats descend from the African wildcat (Felis lybica), a species that had minimal access to large, stagnant water sources. Their ancestors relied on water obtained through prey and sought out safe, moving streams when possible. This innate preference remains strong in modern cats.
Moving water vs stagnant water — safety and survival
In the wild, still water is more likely to carry harmful bacteria, parasites, or contamination. Running water, by contrast, naturally filters itself and is far safer. This biological wiring explains why many cats ignore their bowls but drink from taps, shower drips, or garden hoses.
Sensory cues: sound, movement, and scent dispersion
Water that flows makes a faint sound and produces tiny movements across the surface. Cats’ sensitive hearing and excellent low-light vision make flowing water easier to detect. The movement also releases subtle scents that help felines identify freshness.
Behavioural studies supporting the preference
Multiple behavioural studies (including observations in multi-cat environments) show that cats drink more frequently and in larger volumes when presented with running water. The preference is remarkably consistent across age groups, breeds, and living environments.
The Science Behind Running Water and Hydration
How running water increases sensory appeal
Cats rely heavily on sensory confirmation before drinking. Running water provides:
- Auditory cues — a soft trickling sound
- Visual cues — surface ripples
-
Tactile cues — coolness and movement
These signals together increase the likelihood that cats will drink.
Why running water tastes “fresher”
As water moves, it becomes aerated. This reduces flat, stagnant flavours that cats instinctively avoid. Aeration also slightly lowers water temperature, which many cats prefer.
The role of oxygenation in palatability
Oxygen-rich water has a “cleaner” profile. While humans can taste the difference subtly, cats are even more sensitive. Oxygenation also slows the growth of biofilm — the slimy residue that forms when water sits still.
How fountains increase daily water intake
Research suggests that water fountains can increase a cat’s daily water consumption by 20–50%, depending on:
- Fountain design
- Flow style (stream, bubble, trickle)
- Bowl material
- Household temperature
This directly supports kidney flushing and urinary tract health.
Veterinary insights
Many vets in Australia recommend fountains for cats prone to:
- Urinary tract infections
- Crystals (struvite, calcium oxalate)
- Early kidney disease
- Low-frequency drinking habits
Hydration remains one of the most protective factors in feline urinary health.

Health Benefits of Drinking More Water
Prevention of urinary crystals and blockages
Concentrated urine increases the risk of crystals forming. Running water encourages frequent drinking, diluting urine and reducing particle formation.
Reduced risk of chronic kidney disease (CKD)
CKD is one of the most common issues in older Australian cats. Proper hydration helps the kidneys flush toxins efficiently, slowing disease progression.
Improved digestion and stool consistency
Hydrated cats digest food more efficiently and produce softer stools, reducing the likelihood of constipation.
Hydration support for dry-food-fed cats
Dry food contains only around 6–10% moisture, while wet food contains 70–80%. A cat eating mostly kibble must drink more to compensate for the moisture deficit — fountains help achieve this balance.
Senior cat support
Older cats often lose their thirst drive. Encouraging them through flowing water can help maintain urinary and kidney health.
Why Cat Water Fountains Work So Well
Consistent filtration removes odours and contaminants
Modern fountains use multi-stage filters (charcoal, sponge, activated carbon) to maintain freshness. This removes:
- Hair
- Debris
- Odours
- Micro-particles from tap water
Flowing water supports natural behaviour
Cats instinctively drink more when they trust the water source. Movement mimics the safety of streams.
Multiple drinking angles
Most fountains provide different access points — a bubbling top, a flowing stream, and a still basin — ideal for multi-cat homes or picky drinkers.
Automatic and continuous-flow options
Some fountains offer:
- Timer-based flow
- Motion sensors
- Quiet pumps
- USB-powered motors
- Adjustable flow settings
This keeps water fresh day and night.
Types of Cat Water Fountains Explained
Gravity fountains
Simple, non-electric designs that refill automatically as your cat drinks. Best for backup use or low-tech households.
Electric motor fountains
These are the most effective, offering continuous flow, dripping streams, or bubbling water movement.
Material comparison
| Material | Benefits | Considerations |
|---|---|---|
| Stainless steel | Hygienic, durable, easiest to clean | Slightly heavier |
| Ceramic | Stylish, weighted (less tipping) | Can chip if dropped |
| BPA-free plastic | Lightweight, affordable | Needs more frequent cleaning |
Quiet-flow options
Ideal for homes where noise may startle shy cats or cause disruption.
Fountains for multi-cat households
Look for models with multiple spouts or wide drinking basins to prevent crowding.
How to Choose the Right Fountain (Australia-Specific Guidance)
Consider local water hardness
Parts of Australia — especially Perth, Adelaide, and regional QLD — have harder water. Choose a fountain with replaceable limescale filters if you live in these regions.
Filter availability
Some imported fountains have filters that are difficult or expensive to replace in Australia. Choose models with widely available filter packs (such as those stocked at PetCareShed).
Electrical compatibility
Australian-standard plugs, safety certifications, and low-voltage USB options are essential.
Home layout considerations
Smaller apartments may benefit from compact designs, while larger homes can accommodate multi-cat fountains with larger reservoirs.
Indoor vs outdoor
Outdoor use requires:
- Heavier materials
- Stronger flow pumps
- UV-resistant plastics
How to Encourage Your Cat to Use a Fountain
Placement is key
Cats prefer water sources away from their food. Place the fountain:
- In a quiet area
- Away from litter boxes
- Near natural light, if possible
- On a non-slip mat
Gradual introduction
- Allow your cat to observe the fountain while it is turned off.
- Switch it on after a day or two.
- Let your cat approach at their own pace.
Use gentle encouragement
- Place an ice cube in the fountain to create movement.
- Offer treats near the fountain to build positive association.
- Avoid flavoured water additives unless recommended by your vet.
Avoid strong scents
Cats are sensitive to chemical smells, so avoid scented cleaners or strong detergents in or around the fountain.
Maintenance & Hygiene — Keeping the Fountain Safe
Cleaning frequency
Most fountains should be cleaned every 5–7 days, especially in warmer climates.
Filter replacement
Replace filters every 2–4 weeks, depending on water hardness and usage.
Bacteria and biofilm
Biofilm builds quickly in warm Australian homes. Choose stainless steel or ceramic to reduce buildup.
Safe detergents
Use mild, unscented dish soap. Avoid strong chemicals that can leave residue and alter the taste of water.

Common Myths About Cats and Water
“Cats don’t like water”
Cats may dislike being wet, but they often love water movement. Many enjoy watching flowing water or drinking from taps.
“Cats will drink when they’re thirsty”
Cats’ thirst signals are weak. By the time a cat feels thirsty, mild dehydration may already have started.
“Dry food provides enough moisture”
Kibble contains only a fraction of the moisture needed for proper hydration. A cat must drink additional water to stay healthy.
