How To Clean A Cat Water Fountain

Keeping your cat’s water fresh is one of the simplest ways to support their health. A cat water fountain makes hydration more appealing, but only if it’s kept clean. Without regular care, fountains can collect slime, bacteria, and mineral buildup that not only taste bad but also put your cat at risk.

This guide walks you through the exact steps for cleaning your cat’s water fountain. We’ll cover how often to wash it, what supplies you’ll need, how to deep clean, and common mistakes to avoid.

 

Why Cleaning Your Cat Water Fountain Matters

Cats can be picky about water. If their fountain smells off or develops a slimy film, they may stop drinking. That leads to dehydration, urinary tract problems, and kidney stress.

Dirty fountains also harbor:

• Bacteria and biofilm that can irritate your cat’s mouth.
• Algae growth if placed near sunlight.
• Mineral buildup from hard water.

A clean fountain ensures your cat drinks more, stays hydrated, and avoids avoidable vet visits.

 

How Often Should You Clean a Cat Fountain?

Veterinarians recommend a full clean once a week for most households.

• Single-cat homes: Weekly cleaning is usually enough.
• Multi-cat homes: Clean every 3–4 days to prevent odor and slime buildup.
• Heavy droolers or messy eaters: More frequent cleaning may be necessary.

Filters should be replaced every 2–4 weeks, depending on the brand. Always follow your fountain manufacturer’s guide.

Quick tip: If the water looks cloudy, it’s already overdue for cleaning.

 

Supplies You’ll Need

Gather everything before you start. Here’s a simple cleaning kit:

• Mild, unscented dish soap
• Vinegar or baking soda (for deep cleaning)
• Soft brush set or sponge
• Microfiber towel for drying
• Replacement filters (keep extras on hand)

Optional but helpful:

A dedicated pet fountain cleaning kit (often includes mini brushes for the pump).

 

Step 1: Disassemble the Fountain Safely

Unplug the fountain before handling. Remove each part carefully:

1. Take off the top cover.
2. Lift out the bowl or basin.
3. Detach the pump.
4. Remove the filter housing.

Keep parts grouped so reassembly is easy later.

 

Step 2: Wash Each Component

Now clean every part of the fountain separately.

Cleaning the Pump and Impeller

The pump is the heart of the fountain, and it clogs easily.

1. Open the pump casing.
2. Remove the impeller (tiny rotating blade).
3. Use a small brush to scrub off any slime or hair.
4. Rinse thoroughly under warm water.

Cleaning the Basin and Spout

• Wash the bowl, basin, and spout with mild soap and a sponge.
• Scrub any corners where slime tends to collect.
• Rinse until no soap residue remains.

 

Step 3: Deep Cleaning for Mineral Buildup

If you have hard water, white spots or crust may appear on your fountain.

Vinegar soak method:

1. Mix equal parts vinegar and warm water.
2. Soak plastic or stainless-steel parts for 15–20 minutes.
3. Scrub gently with a brush.
4. Rinse until the vinegar smell is gone.

Baking soda option: Make a paste with water and baking soda to scrub stubborn stains.

 

Step 4: Rinse and Reassemble

Rinse every piece with clean water.

Dry with a towel before putting the fountain back together.

Insert a new filter if it’s due for replacement.

Refill with fresh, cold water.

Plug in and check for smooth operation.

 

Dishwasher-Safe Parts: What You Can and Can’t Wash

Some fountains advertise dishwasher-safe components. Here’s a quick guide:

Always confirm with your fountain’s manual before placing parts in the dishwasher. Avoid harsh chemical washing tablets. They can leave residues that affect taste and may not be pet-safe. Look for eco-friendly cleaners. A good option is Filthy Clean.

Recommended Cleaning Kits and Replacement Filters

Keeping the right supplies on hand makes cleaning faster. We recommend:

• Cat Fountain Cleaning Kit – Includes brushes for pump and spout.
• Replacement Carbon Filters – Swap every 2–4 weeks.
• Stainless Steel or Ceramic Fountains – Easier to clean than plastic.

Troubleshooting Dirty or Smelly Fountains

Even with regular cleaning, issues can arise.

• Persistent slime: Clean more often and avoid placing near direct sunlight.
• Bad odor: Replace filters and deep clean with vinegar.
• Noisy pump: Usually caused by low water levels or debris in the impeller.
• Weak water flow: Check for clogs in the filter housing.

Common Mistakes to Avoid

• Using bleach or harsh cleaners (toxic for cats).
• Forgetting to rinse off soap fully.
• Letting the fountain run dry.
• Using old filters beyond their lifespan.
