Fresh, clean drinking water is one of the most important things to provide for your cat's health. While it may seem trivial, regularly washing and changing your cat's water is essential to preventing the spread of bacteria, viruses, and parasites. Too often, cat parents don't realize how quickly their kitty's water bowl can accumulate harmful germs and become contaminated.

General Cleaning Recommendations

To keep your cat's water fresh and avoid contamination, veterinarians recommend following these general cleaning guidelines:

  • Daily - Empty the water bowl and wash it with hot water and pet-safe dish soap at least once per day. Give the bowl a thorough scrubbing to remove any organic matter or biofilm.
  • Weekly - In addition to daily washing, disinfect the bowl completely once a week with diluted bleach or vinegar. Soak the bowl for 5-10 minutes before rinsing. This will kill parasitic cysts or bacterial growth.
  • Monthly - Along with daily and weekly cleanings, do a deep clean of the bowl once a month. Use a bottle brush or scrubbing pad to remove any mineral deposits or built-up biofilm. This prevents gradual bowl staining.

Of course, these are general timelines. You may need to adjust the frequency based on factors unique to your cat and its environment. Sticking to a consistent schedule is key for maintaining proper water hygiene. Don't forget to change the water.

Factors that Determine Cleaning Frequency

While the general guidelines provide a good baseline, there are several factors that play a role in determining just how often your cat's water bowl needs washing:

  • Number of Cats - If multiple cats are sharing the same water source, clean it more often. The more cats using a bowl, the quicker bacteria and viruses can accumulate. Disinfect shared bowls daily.
  • Bowl Material - Plastic bowls tend to scratch and can harbor bacteria more than stainless steel. Stainless steel or ceramic bowls may only need weekly disinfecting.
  • Water Source - Filtered or circulating water requires less frequent cleaning than standing water. A multi-cat fountain may only need cleaning 1-2 times a week.
  • Location - Outdoor water bowls collect more debris and soil microbes. Outdoor bowls likely need daily scrubbing.
  • Health Issues - Cats with weaker immune systems or illnesses may necessitate more frequent bowl disinfection, even twice a day.
  • Diet - Cats fed canned food shed more microbes and organic matter into the bowl. Clean more diligently for cats on wet diets.

Adjust the schedule based on these factors to meet your specific cat's water hygiene needs. When in doubt, err on the side of caution and wash the bowl more often.

Improving Hydration with a Water Fountain

While diligently washing your cat's water bowl is crucial, you can also improve your feline's hydration by using a water fountain. Some details you would like to know: Water Bowls vs Drinking Fountains.

Cat fountains provide a constant circulating stream of filtered water, unlike a stagnant bowl. The moving water encourages cats to drink more, since it mimics natural drinking sources.

The constant circulation also inhibits bacterial growth. The filtration removes contaminants and debris that would normally accumulate in standing water.

However, water fountains still require regular cleaning like a normal bowl. Follow the manufacturer's directions for changing filters and cleaning the pump. Scrub the fountain weekly to prevent biofilm buildup.

By combining a fountain with proper water bowl hygiene, you can optimize hydration for your cat's health and happiness. The fountain encourages drinking, while cleanings curb bacteria spread. Together, they ensure your cat stays healthy and well-hydrated.


Proper water bowl hygiene is imperative for any cat owner. By washing your cat's water bowl frequently, you can help prevent the spread of harmful bacteria, viruses, parasites, and other contaminants. Make sure to clean the bowl thoroughly each day with hot water and pet-safe soap, disinfect weekly with diluted bleach or vinegar, and do a deep scrub monthly.

Consider adding a water fountain to encourage your cat to drink more. Fountains provide filtered, circulating water. Combining fountain use with diligent bowl washing is ideal for feline health. Proper water hygiene is one of the best investments you can make in your feline companion's wellbeing.
