Can I Keep My Pet Fountain On Constantly? Expert Advice for Owners

If you’ve got a cat at home, you’ve probably noticed they’re picky about water. Some barely touch their bowl unless the water is fresh. This is one reason cat water fountains are so popular — moving water just seems to get their attention.

Now, here’s the big question many cat owners ask: Can you just leave the fountain running all day, every day?

The short answer — yes, you can. Nevertheless, there are a few points to remember to make sure that your furry friend is safe and the fountain lasts long. 

Why Keep It Running?

Cats are more likely to drink from running water. The sound, the movement — it’s like their instincts kick in and they think, “This is safe to drink.” Still water, on the other hand, can go stale fast. That is a recipe for bacteria in warmer months.

By leaving the fountain on, the water continues to circulate, which reduces the speed of nasties’ growth. It also prevents dust and pet hair from sitting on the surface. And, in case your cat likes to take only a few sips at a time, then keeping fresh water around at all times can help your cat stay hydrated and prevent urinary issues.

Is It Safe to Leave It ON?

Most decent cat fountains are built to run 24/7. The pumps are small and low‑power, not unlike what you’d find in an aquarium. The danger isn’t from them being on all the time — it’s from neglect.

If the water level drops too low, the pump can run dry and overheat. If you let the inside get dirty, bacteria can build up despite the water moving. And, of course, you don’t want an electrical cord sitting in a puddle.

Tips to Keep It Safe

Here’s what I’ve learned after a few years of using cat fountains:

1. Keep an Eye on the Water Level

Don’t assume the water will last a week. In summer or with more than one cat, it can drop quickly. A pump running without enough water won’t last long — and it might make a loud buzzing sound before it quits.

2. Clean It Regularly

Running water doesn’t mean clean water. Every week, take it apart and give it a good scrub with warm, soapy water. Make sure you rinse well — cats can be picky about soap smells.

3. Swap the Filters

If your fountain has filters, they’re not just for show. They trap fur, dust, and bits of food, but they don’t last forever. Most need is to change filters every two to four weeks.

4. Use Fresh Water

Don’t just top up from the tap forever. Every few days, empty it and start fresh. Cats notice taste changes more than you’d think.

5. Place It Wisely

Keep the fountain somewhere stable, away from power strips or spots where water could splash onto cords. Some cats like to splash or paw at the stream, so think about that too.

Energy Consumption 

Worried about the electric bill? Don’t be. Most pumps use just a couple of watts. Leaving it on 24/7 usually costs less per year than running a single light bulb for a few days.

If you still want to save a little, you could turn it off at night — but keep in mind some cats like a midnight drink.

When to Switch It Off

There are a few situations where it’s better not to leave the fountain running:

• You’re away for more than a day, and no one can check the water.

• The pump is making odd noises — that means it’s struggling.

• You’re cleaning it (always unplug before touching anything inside).

Signs It Needs Attention

• The water smells off.

• The stream is weaker than usual.

• Your cat won’t go near it anymore.

Any of these is a sign it’s time for cleaning or a water change.

The Importance of a Cat Water Fountain

Cats are independent creatures, but they depend on us when it comes to water. A bowl of stale water may get stale quickly. On the other hand, running water remains fresher much longer, and most cats will instinctively like it.

A fountain will make your cat drink more frequently. The movement maintains the water oxygenated and attractive, and the sound can even serve as a reminder to them that it is time to take a drink.

The WOpet Pet Water Fountain is one of the options that should be considered. It is quiet, simple to clean, and pet-safe. The in-built filter prevents fur and debris from entering the water, hence your cat will have fresh, clean water each time.

The Bottom Line

In conclusion, leaving your cat’s water fountain on all the time has both benefits and drawbacks. Acat water fountain provides your pet with clean, fresh, and running water, which can help with hydration and encourage your cat to drink more water. 

It is important to maintain the cleanliness and water level of the fountain, and to use filtered or tap water to ensure that your pet is drinking clean water.
