How to Keep Your Cat’s Water Fountain Flowing Clean

Cats love running water, so a clean fountain keeps them hydrated and happy. The main problem is slime-biofilm that builds inside the pump and slows flow.
Cleaning is straightforward. First unplug the fountain and drain all water. Disassemble the pump, removing the propeller with tweezers if needed. Wash each part with warm water and a few drops of mild dish soap, or soak for 10-15 minutes in a 1:1 water-vinegar solution. Rinse thoroughly to remove any vinegar scent. Reassemble, refill the bowl, and plug the unit back in.
The Ohio State University Indoor Pet Initiative recommends a full pump cleaning every one to two weeks to prevent biofilm and mineral buildup. Some owners also run a vinegar solution through the fountain to help clear slime, a method also endorsed by International Cat Care.
Regular cleaning keeps the pump efficient and the water safe for your cat.
Key takeaways
- Biofilm slime builds inside the pump and slows water flow.
- Disassemble, wash with soap or a 10-15 minute vinegar soak, rinse, and reassemble.
- Clean the pump every 1-2 weeks to maintain flow and water quality.
