Key Takeaways
- Domestic cats have a naturally low thirst drive, making dehydration common and significantly increasing the risk of UTIs and kidney disease.
- Running water from fountains stimulates a cat’s instinct to drink more, supporting urinary tract health and reducing the likelihood of crystal formation, blockages, and kidney strain.
- Water fountains oxygenate, filter, and circulate water, keeping it fresher and more appealing than stagnant bowls.
- Increased hydration leads to more dilute urine—this lowers inflammation, bacterial growth, and mineral accumulation.
- Using a water fountain, alongside diet, enrichment, and proper vet care, is one of the most effective long-term strategies for urinary health in indoor cats.
Where Comfort Meets Care — PetCareShed’s Feline Picks
Introduction
Urinary tract issues and kidney problems are among the most common health concerns in domestic cats, especially indoor cats. Many Australian cat owners are surprised to learn that a large portion of these issues stem from a simple cause: not drinking enough water. Cats descend from desert-dwelling ancestors, and while that lineage helped them survive harsh environments, it also means today’s cats often fail to meet their daily hydration needs.
A modern solution—cat water fountains—has proven to be remarkably effective in increasing feline water intake. This article explores the science behind why running water works, how fountains support urinary and kidney health, and what features matter when choosing one.
Understanding Why Cats Are Prone to UTIs and Kidney Problems
Evolutionary Background: Low Thirst Drive
Cats evolved in arid climates where water was scarce. They survived by obtaining moisture from prey, which typically contains 60–70% water. As a result, cats naturally:
- Do not feel thirsty until dehydration is already significant.
- Produce highly concentrated urine.
- Tend to ignore standing water unless extremely thirsty.
In a domestic setting—especially in Australia, where many cats live indoors and eat mainly dry food—this low thirst drive becomes a health risk.
Common Urinary Tract Issues in Cats
Several urinary disorders are directly linked to hydration levels:
Feline Lower Urinary Tract Disease (FLUTD)
An umbrella term covering inflammation, urinary blockages, and bladder issues.
Urinary Tract Infections (UTIs)
Bacterial infections caused by concentrated urine, inflammation, or incomplete bladder emptying.
Crystals and Stones
The two most common types:
- Struvite crystals (magnesium ammonium phosphate)
- Calcium oxalate crystals
Both can form painful stones when urine is too concentrated.
Chronic Kidney Disease (CKD)
One of the most prevalent age-related diseases in cats, heavily influenced by long-term hydration habits.
Role of Dehydration in Urinary Problems
When a cat is dehydrated:
- Their urine becomes highly concentrated, irritating the bladder.
- Minerals build up more easily and form crystals.
- Bacteria thrive in the stagnant environment.
- The kidneys must work harder to filter toxins.
Simply increasing hydration is one of the most effective preventative measures against urinary illness.

Why Running Water Encourages Cats to Drink More
Instinctual Attraction to Moving Water
In nature, running water is almost always safer to drink than still water. As a survival instinct, many cats are drawn to:
- Streams
- Drips
- Cascades
- Flowing water sounds
This instinct explains why some cats try to drink from taps—even when they ignore their bowl.
Taste and Freshness
Standing water quickly starts to taste “stale” due to:
- Dust
- Food particles
- Bacteria
- Saliva contamination
Water fountains solve this by:
- Constantly circulating water
- Filtering debris and chemicals
- Increasing oxygen content
This makes the water taste and smell fresher, encouraging cats to drink more.
Visual and Auditory Stimulation
Flowing water stimulates a cat’s senses:
- Movement catches the eye
- Trickling water attracts curious cats
- Sound cues them that fresh water is available
For anxious or picky cats, the gentle flow can be reassuring and enriching.
How Water Fountains Support Urinary and Kidney Health
1. Increased Hydration
The primary benefit of water fountains is simple: cats drink more.
More hydration = more dilute urine.
Dilute urine reduces:
- Irritation
- Bacterial growth
- Crystal formation
- Bladder inflammation
2. Prevention of Urinary Crystals and Stones
Mineral crystals form when urine is:
- Too concentrated
- Too alkaline (struvite)
- Too acidic (oxalate)
Water fountains help maintain proper urine concentration, making crystallisation far less likely.
3. Reduced Inflammation in the Urinary Tract
Hydrated bladder tissues are healthier and less prone to inflammatory flare-ups associated with FLUTD.
4. Long-Term Kidney Protection
Kidneys rely on hydration to flush toxins efficiently. Adequate water intake helps:
- Reduce kidney workload
- Slow the progression of CKD
- Minimise early kidney stress in young adult cats
5. Better Appetite and Overall Behaviour
Cats that drink more often:
- Eat better
- Have more consistent litter box habits
- Stay more active and relaxed
Hydration supports nearly every system in their body.
Water Fountain Features That Matter for Urinary Health
Filtration Systems
The best fountains feature:
- Activated carbon filters for chlorine, odours, and chemicals
- Foam/mesh filters for hair and debris
- Multi-stage circulation for freshness
Filtered water is more appealing and safer.
Water Capacity & Flow Speed
- Single-cat households: 1.5–2.5 litres
- Multi-cat households: 3–4 litres
Adjustable flow speed allows you to match your cat’s preferences—from silent stream to bubbling fountain.
Material Safety
- Stainless steel: Most hygienic, mould-resistant, dishwasher-safe
- Ceramic: Heavy, stable, visually appealing
- BPA-free plastic: Lightweight, affordable, but needs frequent deep cleaning
Noise Levels
Cats can be sensitive to sound. A quiet pump is essential for encouraging consistent use.
Ease of Cleaning
A clean fountain equals healthy hydration. Look for:
- Dishwasher-safe bowls
- Removable motor compartments
- Simple dismantling
- Accessible corners
Dirty fountains quickly become counterproductive.

How to Introduce a Water Fountain to Your Cat
Gradual Introduction Tips
- Place the fountain next to their current water bowl.
- Let the cat sniff and explore while it’s turned off initially.
- Introduce flowing mode later.
- Use the lowest flow setting at first.
Encouraging Reluctant Cats
- Add a few ice cubes for movement.
- Smear a little tuna water around the rim (wipe after).
- Try different fountain materials—some cats prefer steel, others ceramic.
- Reward your cat when they approach or use it.
Additional Ways to Prevent UTIs and Kidney Problems
1. Diet and Moisture Content
Wet food contains 60–70% water, significantly improving hydration.
Veterinarians frequently recommend:
- Wet diet for cats prone to FLUTD
- Prescription urinary formulas
- Combination feeding (wet + dry)
2. Litter Box Management
A clean litter box helps you monitor changes early, such as:
- Blood
- Small clumps
- Frequent small urinations
- Straining or hesitation
Stress-free litter box access also reduces FLUTD risk.
3. Environmental Enrichment
Stress is a major contributor to urinary inflammation.
Helpful enrichments include:
- Window perches
- Scratching posts
- Interactive toys
- Cat trees
- Hiding spots
- Puzzle feeders
4. Routine Veterinary Care
Annual check-ups are essential. Your vet may recommend:
- Urinalysis
- Bloodwork
- Ultrasound (in chronic cases)
- Hydration monitoring
Early detection makes treatment far more effective.

Frequently Asked Questions
Do water fountains actually help prevent UTIs?
Yes. Increased hydration dilutes urine, which lowers inflammation, bacterial growth, and crystal formation—key contributors to UTIs.
Are stainless-steel fountains better for urinary health?
Stainless steel is more hygienic, less porous, and highly resistant to bacteria, making it ideal for cats prone to urinary problems.
How often should I clean a cat water fountain?
Most vets recommend:
- Rinse every 2–3 days
- Deep clean every 5–7 days
- Replace filters every 3–4 weeks
Will a fountain cure an existing UTI?
No. UTIs require veterinary treatment (often antibiotics).
Fountains prevent, not treat.
Can kittens use water fountains?
Absolutely. Kittens benefit from healthy hydration habits early in life, and fountains are safe for all ages.
Conclusion
Hydration is the foundation of urinary and kidney health in cats. Because most cats naturally avoid drinking still water, running water from fountains is one of the simplest yet most powerful ways to protect their wellbeing. Whether your cat is young, senior, prone to UTIs, or just picky about water, a fountain encourages better habits that can prevent years of discomfort and costly medical complications.
By creating a hydration-friendly environment—fountains, wet food, clean litter boxes, and regular vet care—you’re giving your cat a healthier, happier, and more comfortable life.
