Cat water fountain: why it can help your cat drink more water

If your cat walks past their water bowl without much interest, you're not alone—it's a very common behavior in the species. Understanding why can be the first step to improving your companion's hydration.

Why many cats drink little water

Cats are descended from desert animals, adapted to obtain much of the water they need through their food. Therefore, their natural instinct to drink directly from a bowl is weaker than in dogs, for example. This becomes even more relevant for cats fed only dry food, who don't receive extra water through their diet.

Why some cats prefer running water

In nature, still water can mean stagnant or contaminated water, while moving water tends to be fresher and safer. This instinct persists in many domestic cats, who are more attracted to water that moves, bubbles, or drips—hence the success of cat water fountains.

Practical advantages of a water fountain

• Can encourage the cat to drink more frequently throughout the day
• Keeps the water fresher and aerated
• Reduces the accumulation of hair and dust on the surface
• Continuously filters impurities, depending on the model

How to choose a good water fountain

Size

Should be proportionate to the number of cats in the home and the available space. Very small fountains need more frequent refilling.

Material

Fountains are available in plastic, ceramic, and stainless steel. Materials like ceramic and stainless steel tend to accumulate fewer bacteria and odors than plastic, and are easier to keep clean.

Noise level

Cats more sensitive to sounds might be put off by very noisy fountains. Before buying, it's worth checking reviews about the pump's noise level.

Filters

Most fountains use activated carbon filters, which help reduce odors, hair, and particles in the water. These filters have a lifespan and should be replaced regularly, as indicated by the manufacturer.

Cleaning and water change frequency

Even with a fountain, the water should be changed regularly—ideally, a complete cleaning of the fountain should be done at least once a week, removing limescale and biofilm residues. The water itself should be refilled more frequently, especially in multi-cat households.

Best place to put the fountain

Place the fountain in a quiet spot, away from the litter box and, if possible, away from the food bowl. Many cats prefer to have water and food in separate areas, an instinctive behavior related to seeking clean water away from potential sources of contamination.

Common mistakes to avoid

• Not cleaning the fountain regularly enough
• Ignoring filter replacement
• Placing the fountain next to the litter box
• Using very aggressive cleaning products that can leave residues

Hygiene practices to maintain

Use potable water, wash your hands before handling the fountain, and whenever possible, opt for mild detergents or just water and diluted white vinegar to remove limescale, rinsing very well before refilling.

If you notice that, even with the fountain, your cat continues to drink very little water, or if you observe signs of changes in behavior, appetite, or urinary habits, it is best to consult a veterinarian.
