Plenty of cats ignore a perfectly good bowl of water and then try to drink from the bathroom tap. If that sounds familiar, a fountain may help. Not every fountain suits every home, though. Capacity, noise, power source, cleaning and filters all affect whether you will use it every day, and whether your cat will.
This guide walks through each point so you can choose with confidence, whether you end up buying from us or not.
Why a fountain can help
Many cats seem to prefer moving water to still water, and some drink more when it is fresh and flowing. A fountain keeps the water circulating and usually filters out hair and debris. It is not a magic fix, and some cats are happy with a clean bowl. But if your cat is picky, a fountain is a gentle, low-stress thing to try.
1. Capacity: match it to your household
Capacity decides how often you refill. A bigger tank means fewer trips to the sink, which matters if you travel for weekends or have several pets.
- One cat: a tank around 2 to 3 litres is usually plenty.
- Multiple pets: look for a larger tank, or plan on topping up more often.
- Small dogs sharing the fountain: choose a model made for both cats and dogs.
A bigger tank is not always better. Water that sits too long goes stale, so a huge tank for one small cat is not ideal. Whatever the size, check the water level every day.
2. Noise: think about your cat and your bedroom
A pump that hums can bother light sleepers. It can also put off a nervous cat who is already wary of a new object. If the fountain will sit in a bedroom, an open-plan living space or near your cat's favourite napping spot, quiet operation matters.
Brands often describe their fountains as “silent” or “whisper-quiet”, but real noise depends on the pump, the water level and the surface underneath. Some practical tips:
- Keep the tank filled above the minimum line, because a low level makes pumps louder.
- Put the fountain on a flat, stable surface, or on a small mat to dampen vibration.
- If you hear rattling or gurgling, check for trapped air or a blocked pump.
3. Cordless or plug-in?
This is the biggest practical decision.
Cordless (rechargeable) fountains give you freedom. There is no cable to chew, trip over or hide, and you can put the fountain where your cat actually wants to drink. The trade-off is that you need to recharge it. Look at the battery capacity and the charging method (USB or USB-C is convenient), and decide whether you are happy to add recharging to your routine.
Plug-in fountains run continuously without a battery to think about. They suit homes with an outlet close to the ideal spot. The downside is the cord. Curious cats and puppies can chew cables, so tuck them away or use a cord cover.
If you have a cat that likes to chew, or you simply dislike visible cables, cordless is worth a look. If you prefer to set it up and forget it, plug-in is simple.
4. Cleaning: the factor people underestimate
A fountain only helps if it is clean. Biofilm and residue can build up in any pet water setup, so choose a model you can take apart easily. Before you buy, check:
- How many parts there are, and whether they come apart without tools.
- Whether the pump can be reached and rinsed.
- Whether the tank opening is wide enough for a hand or a small brush.
A simple routine works for most homes: empty the fountain, take it apart, wash the pieces with warm water and a mild, unscented dish soap, rinse thoroughly, and let everything dry before reassembling. Follow the manufacturer's instructions for the pump. Top up with fresh water between deep cleans rather than just adding to old water.
5. Filters: what they do and what they cost you
Filters help catch hair and particles and can improve how the water tastes. They do need replacing, so check how many replacement elements come with the fountain and whether you can easily buy more. A used-up filter is worse than no filter, so follow the replacement guidance for your model.
Also consider whether the design separates clean water from waste water, and how the water gets from the tank to the bowl.

How to introduce a fountain gently
Cats can be wary of anything new, so go slowly.
- Place the fountain near the current water bowl and leave the old bowl in place for a few days.
- Let your cat investigate in their own time. Do not push their face toward the water.
- If the fountain has adjustable flow or timers, start with the gentlest setting that works.
- Once your cat is drinking from it regularly, you can remove the old bowl, or keep it as a backup.
Keep water away from food bowls, since many cats prefer to drink some distance from where they eat.
When to talk to your vet
A fountain is a convenience, not a medical tool. If your cat suddenly drinks much more or much less than usual, seems lethargic, loses weight, or has changes in urination, see your veterinarian. These can be signs of health problems that need professional attention, and a new fountain will not fix them.
Frequently asked questions
Do cats really prefer fountains?
Some do, and some do not. Many cats are drawn to moving water, but every cat is different. Introduce the fountain gradually and keep the old bowl available at first.
How often should I clean a cat water fountain?
Check it daily and top up with fresh water. Do a full clean on a regular schedule, often weekly, and more often if you have several pets or see residue. Always follow the manufacturer's care instructions.
Are cordless fountains as reliable as plug-in ones?
They can be, as long as you recharge them when needed. The main difference is convenience: cordless gives you placement freedom, while plug-in removes the need to charge.
Can a dog use a cat fountain?
Some fountains are designed for both cats and dogs, usually small ones. Check the product description, and make sure the capacity is enough for the size of your dog.
