Share
A cat water fountain can encourage your pet to drink more water by providing fresh, circulating water.
However, many cat owners have the same question:
"How do I keep a cat water fountain clean?"
Unlike a traditional water bowl, a fountain contains multiple components:

The good news is:
Cleaning a cat water fountain is much easier than many owners expect.

🧽 Step-by-Step Guide: How to Clean a Cat Water Fountain
Step 1: Disconnect and Disassemble the Fountain
Before cleaning:
🔌 Turn off the power
💧 Remove remaining water
🧩 Separate removable parts
Most modern fountains are designed with detachable components for easier cleaning.
Step 2: Wash the Water Tank
The water tank collects:
- Dust
- Cat hair
- Saliva residue
- Mineral deposits
Use:
✅ Warm water

✅ Soft sponge
Avoid harsh chemicals that may leave strong odors.
Step 3: Clean the Pump System
The pump is one of the most important parts of a fountain.
Over time, it may collect:
- Hair
- Small particles
- Mineral buildup
A dirty pump can cause:

⚠️ Shorter lifespan
Remove the pump cover and gently clean the internal components.
Step 4: Replace or Wash the Filter
Filters help remove:
🧽 Hair
🌫 Dust
💧 Unpleasant odors
However, filters are not permanent.
A filter that has been used too long may become less effective.
