Quick answer

A water fountain for cats encourages your cat to drink more through flowing water, which helps prevent kidney problems in the long term. When choosing, pay attention to sufficient capacity, a wireless pump (no cord in the water), a replaceable filter and a quiet motor.

✓2.5–3 litres is sufficient for 1 to 2 cats
✓Wireless pump is safer than a cord through the water reservoir
✓Replace filter every 2 to 4 weeks for clean, tasteless water
✓Quiet motor prevents stress and helps with acclimatisation

A cat drinks on average 50 to 60 millilitres of water per kilogram of body weight per day. In practice, most cats drink far less than that. A water fountain changes that. Flowing water attracts cats and encourages them to drink more often, which has direct consequences for their kidney health in the long term.

Why do cats prefer running water?

In the wild, cats prefer to drink from running water, not from stagnant puddles. Stagnant water is more likely to be a source of bacteria in nature. Cats still have this instinct, even if they live in a flat.

A normal water bowl sits still. Cats sniff it, walk past it and only drink from it when they are really thirsty. A water fountain continuously circulates the water. The sound and movement attract cats, even when they are not actively thirsty.

💧

Kidney disease is the most common condition in cats over 7 years old.

Chronic mild dehydration is one of the main causes. Drinking more requires little effort from cats if the water is moving. A water fountain is therefore not just a gadget, but a preventive health investment.

Water fountain vs. regular water bowl

	Regular water bowl	Water fountain
Water change	Daily or more often	Automatic via circulation
Bacterial growth	Quickly in stagnant water	Slowed by filter + movement
Cat drinking behaviour	Low, only when thirsty	Higher, several times a day
Maintenance	Daily rinsing	Weekly + filter replacement
Weekend away	No, water sits still	Yes, 2.8L lasts a long time

What to look for when buying?

Capacity

For 1 to 2 cats, 2.5 to 3 litres is sufficient. If you have 3 or more cats, consider a model with more capacity or place two fountains.

Wireless or with cord?

⚡

Wireless is safer and cleaner.

The D600A from Prime AnimalZ is completely wireless: the motor is inside the device and no cord runs through the water reservoir. This makes cleaning easier and eliminates the risk of a damaged cord in the water.

Filter

We recommend replacing the filter every 2 to 4 weeks, depending on usage and number of cats.

Sound

Choose a model with a quiet circulation pump, especially if you place the fountain in a small room.

Ceramic or plastic?

Always choose BPA-free plastic. With a wireless pump and regular cleaning, a plastic water fountain is fine for most cats.

Who is a water fountain most suitable for?

Cats that drink little

Most owners see a difference within a week.

Older cats

Kidney problems are the most common condition in cats over 7 years old. Preventively drinking more water helps.

Households with multiple cats

A water fountain with sufficient capacity ensures that fresh, circulated water is always available for all cats.

Owners who are regularly away

A water fountain with 2.8 litres will last a whole weekend for one cat.

Frequently asked questions

How much water does a cat need per day?+

A cat needs on average 50 to 60 millilitres of water per kilogram of body weight per day. A 4 kg cat therefore needs about 200 to 240 ml per day. Cats that eat dry food need more water than cats that eat wet food, as dry food contains almost no moisture.

How do I clean a water fountain?+

Rinse the reservoir thoroughly with warm water weekly. Every two weeks remove the pump and clean it separately. Read our article on cleaning a water fountain.

How often do I need to replace the filter?+

With 1 cat: every 3 to 4 weeks. With 2 cats: every 2 weeks. A worn-out filter filters less effectively and can itself become a source of bacterial growth.

What if my cat doesn't want to drink from it?+

Place the fountain next to the regular water bowl for a few days. A week of patience is almost always enough.
