For many cat owners, a water fountain is a convenient and effective way to ensure their pets stay hydrated while keeping water fresh and clean. However, owning a cat water fountain also means taking responsibility for its maintenance and upkeep to ensure your furry friend's health and safety. Optimal hygiene is crucial for cat water fountains, as they can become breeding grounds for harmful bacteria if not cleaned properly.

This article will explore the best practices for maintaining your cat's water fountain and ensuring it remains in excellent condition for years. By following these steps, you'll feel confident knowing your cat always drinks high-quality water from a clean, well-maintained water fountain.

Cat Water Fountain Maintenance

Daily Maintenance

Keeping your cat's water fountain clean and operating properly is essential to ensure your furry friend enjoys fresh, healthy water every day. Here are the key parts of the daily maintenance routine for your pet water fountain:

  • Wipe down the entire unit using a damp cloth to remove any accumulated dust, hair, or debris. Pay special attention to the water basin, spill tray, and exterior surfaces that your cat may contact. A microfiber cloth is gentler on surface finishes.
  • Empty out all the standing water in the basin and reservoir by unplugging the fountain, popping out the basin, and lifting out the reservoir. Thoroughly rinse both parts with lukewarm water before refilling the reservoir with fresh water. This helps remove any germs or stray food particles.
  • Avoid using harsh soaps, bleaches, or abrasive sponges when cleaning your cat's water fountain. These can ruin electronics and leave behind residues that alter the water's pH, irritating your cat's delicate system. Stick to a damp cloth and plain water for routine maintenance.
  • Replace the filter cartridge inside the unit as directed - typically every 2-4 weeks. Filters help remove minerals, chemicals, and sediments from the water to keep it fresh and clean for your cat. Changing filters regularly is key to optimizing the fountain's performance.

Weekly Maintenance

While daily wiping and refilling of your cat's water fountain are essential, periodic deep cleaning is also needed to remove lingering buildup and prevent bacteria growth. A thorough weekly maintenance routine for your pet fountain should include:

  • Completely disassembling the unit by removing the basin, pump, and reservoir. Set aside any electrical parts and focus on washing the individual plastic and metal components. This allows for a more thorough cleansing.
  • Soaking the basin, pump, and reservoir parts in hot, soapy water for several hours. Use a mild, pet-safe dish soap and warm water (around 100°F) to loosen any mineral deposits, residue, or stuck-on debris. Let the parts soak for a few hours or overnight for maximum effect.
  • Scrubbing each part individually using a bottle brush or toothbrush. Focus your scrubbing on the interior basin where biofilm can accumulate, as well as narrow spouts and crevices. Gently remove debris and buildup without scratching or damaging the finish.
  • Rinsing all parts thoroughly under running water before reassembling the fountain, ensuring no soap residue remains. Use a stainless steel scrubber to scour off any lingering debris or stains.
  • Allow all parts to air dry completely before reassembling your cat's water fountain. This helps kill any remaining bacteria as well as prevent corrosion from trapped water.
  • Performing a weekly deep clean for your furry friend's drinking fountain helps remove buildup that can harbor bacteria and parasites over time. Following the disassembly, soaking, scrubbing, and thorough rinse steps will help extend the fountain's lifespan while always providing your cat with fresh, clean water.

Monthly Maintenance

Once a month, take some time to do a more thorough inspection and cleaning of your cat's water fountain. This will help catch any small issues before they become bigger problems.

Inspect the entire unit for any cracks, leaks, or damaged parts. Check the basin, tubing, pump, and reservoir for signs of wear and tear. Now is the time to replace any cracked, corroded, or excessively stained parts.

Clean any hard-to-reach areas using a simple solution of one part white vinegar to two parts water. Soak a cloth in the solution and wipe down crevices, spouts, and filters. The mild acidity of the vinegar helps cut through soap scum, stains, and mineral deposits.

Run the pump without the basin to ensure a constant stream of water flows. Check for any obstructions in the tubing or blockages in the pump itself. Optimal flow helps aerate the water and keep it fresh for your cat.

Disinfect the area surrounding the fountain by wiping down nearby surfaces with antibacterial wipes. This helps prevent bacteria growth that could contaminate your cat's water.

Seasonal Maintenance

For optimal performance over the lifespan of your cat's water fountain, seasonal cleaning and maintenance are recommended.

Perform a thorough inspection of all parts for damage or wear after long periods of non-use. Check for cracks, corrosion, leaks, or clogs that could allow bacteria to fester. Thoroughly clean and, if needed, replace parts as directed in your fountain's manual.

Store the fountain in a dry, cool place when not in use for weeks or months. High temperatures and humidity can accelerate the corrosion of metal parts. Keep water out of the basin, reservoir, and pump to prevent mold and algae growth.

Consider replacing the entire fountain every 2-3 years for maximum hygiene and performance. Minerals, debris, and biofilm buildup over time can impact water quality and flow, even with regular cleaning.

To store a fountain safely:

  • Empty and dry all parts completely. Remove and clean the filter before storage.
  • Disassemble the fountain and wrap the individual parts separately in dry cloth or Bubble wrap.
  • Store in an upright position in a frost-free area to preserve any seals and O-rings.
  • Remove batteries from electronic or automated fountains.


Proper cat water fountain maintenance through daily wiping, weekly deep cleans, monthly inspections, and seasonal storage will ensure your furry friend can access clean, fresh water for years. By following these best practices, you can provide your cat with the healthy hydration they need while extending the usable lifespan of the fountain itself.
