Kun je de drinkfontein van je kat buiten zetten in de zomer?
During the heatwave plaguing Belgium this summer, many cats seek coolness in the garden or on the terrace. It's logical to wonder if you can simply take the drinking fountain outside so your cat also has fresh, running water there. Short answer: yes, provided you follow a few safety rules.
📌 In short
- An outdoor drinking fountain is possible, but place it in the shade and out of direct sunlight.
- Preferably choose a wireless, battery-powered model if there is no safe outdoor power outlet.
- Change the water more often: in the heat, bacteria and algae grow faster.
- Protect electrical components from rain and thunderstorms — showers are predicted this weekend.
- Bring the fountain indoors at night or during severe weather.
Can a cat drinking fountain be placed outdoors?
Yes, a cat drinking fountain can be placed outdoors as long as it is protected from direct sun, rain, and dirt. Cats naturally prefer to drink running water, and offering a fresh water source outdoors helps prevent dehydration during hot days.
It is important to remember that a fountain remains an electrical appliance. A wired model should only be placed outdoors if you have a power outlet with earthing and good rain protection. If not, a wireless, battery-powered fountain is the safest choice.
Where is the best place to put the drinking fountain outdoors?
Place the fountain in the shade, on a flat, stable surface, away from the feeding area and the litter box. A spot under a canopy, on the terrace, or against the facade keeps sun and rain away and keeps the water cooler for longer.
Avoid sandy or dusty spots: grit and pollen would otherwise quickly end up in the reservoir and cloud the water. You can read more about the ideal location in our article where to best place your cat's drinking fountain.
💡 Tip: Add a few ice cubes to the reservoir or use chilled water to keep the temperature extra low on hot days. This keeps the water appealing to drink.
Which drinking fountain is suitable for outdoors?
A wireless, battery-powered model is most suitable for outdoors, as you don't need a power outlet or cable. This avoids tripping hazards and allows you to easily move the fountain to the shade or indoors.
The AquaPaw 2.5L runs on a rechargeable battery, making it ideal for the terrace or garden. For permanent indoor setups or on a covered terrace with a power outlet, the stainless steel FlowMate Pro and HydroBuddy are excellent choices.

Change the outdoor water at least once a day and rinse the reservoir more often, as heat and pollen accelerate bacteria and algae growth. Also regularly check the filter, which gets saturated faster in the summer.
More cleaning routine can be found in how to keep your cat's water cool in the summer. If you're unsure about filter frequency, read how often to replace your drinking fountain's filter.
⚠️ Beware of thunderstorms and rain
This weekend, local thunderstorms and showers are predicted in Belgium. Always bring an electric fountain indoors during rain, thunderstorms, or at night. Water and electricity do not mix, and a wet battery or adapter can malfunction.
Frequently Asked Questions
Can a drinking fountain be placed in direct sunlight?
No. Full sun heats the water, accelerates algae growth, and can damage plastic parts or the battery. Always place the fountain in the shade.
Can my cat drink from a regular bowl instead of a fountain outdoors?
That's possible, but stagnant water heats up faster and gets dirty quicker. Cats generally drink more from a fountain with running, cool water.
How often should I change the water outdoors?
In the summer, at least once a day, and more often if a lot of dust, pollen, or insects get into the water.
Does a battery-powered fountain work all day outdoors?
A fully charged AquaPaw lasts several days depending on the setting. For outdoor use on a hot day, it's best to fully charge it in the morning.
