The dog’s water bowl may be one of the dirtiest items in the house, but a cat’s water bowl can get pretty disgusting, too. If you’ve noticed your kitty’s drinking vessel looking a little slimy these days, have you ever wondered why?
In this article, we’ll cover three likely reasons your cat’s water bowl gets slimy that go from having old water in the bowl to a lack of cleaning. We’ll also let you know if the slime is dangerous to you or your cat and how to prevent it from building up.
The 3 Reasons Your Cat’s Water Bowl Gets Slimy
1. Old Water
If the water in your cat’s bowl goes unchanged for too long, the bowl can become slimy. Dogs drink so much water that you have to refill it often. Ideally, cats should drink 3.5-4.5 ounces of water per 5 pounds of body weight each day.
If the bowl holds 8 ounces of water, a 10-pound cat should just about empty it each day. However, many cats don’t drink enough water, especially if they eat canned food, which supplies much of the liquid they need. Under those circumstances, it’s easy for the water to get old as it sits out for long periods, which increases the chances of the bowl getting slimy.
Solution: Give your cat fresh water daily, no matter how empty the bowl is. To encourage your cat to drink, consider purchasing a cat water fountain. Many cats enjoy drinking moving water more than stagnant water. You could also ask a vet if adding broth or tuna juice to your cat’s water is okay to make it taste more flavorful.

2. Bowl Hasn’t Been Washed
You would not expect your dishes to stay clean if you never washed them, would you? Your cat’s water bowl is no different. If you don’t wash it, it will get slimy. If your cat eats wet food, you probably already wash your kitty’s food bowl frequently to remove crusted, smelly leftovers.
It might not be as easy to remember to clean the water bowl, but it’s just as important. Dirty bowls can impact the flavor of the water, making your cat less likely to drink.
Solution: Wash your cat’s water bowl at least once a week. To make your life easier, look for dishwasher-safe bowls. If you hand wash the bowl, use hot water and regular dish detergent, but rinse it thoroughly.
3. Biofilm
Over time, the combination of dirty water, lack of cleaning, and your cat’s saliva can develop biofilm, which is a slimy coating on the water bowl. A biofilm develops from multiple types of bacteria floating around your cat’s bowl. The organisms bind together, forming a slime that sticks to surfaces like the water bowl.
Both harmful and beneficial bacteria may be present as part of the biofilm, and the possibility of dangerous organisms means you should not take any chances with the slime build-up.
Solution: Frequent wiping and washing of the water bowls will keep biofilm from taking hold. We already mentioned washing the bowl at least once a week, but even a quick wipe with a paper towel can keep biofilm slime from developing. Stainless steel water bowls are more resistant to biofilm.
Cats can be very particular about many things, including the water they drink. The right water fountain can provide your cat with clean, fresh water.

Is the Slime in the Water Bowl Dangerous?
Unfortunately, the biofilm in your cat’s water bowl can harbor dangerous bacteria. E. coli, Listeria, and other organisms can cause illnesses in humans and cats. Studies of biofilm found that plastic bowls developed the most bacteria, while ceramic bowls spawned the most dangerous strains of bacteria, including antibiotic-resistant strains.
The longer you use the same water bowl, the higher the chance that dangerous slime could develop, especially if you neglect your cleaning regimen.
Conclusion
Slimy cat water bowls may be unpleasant, but they are also easy to avoid. Now that you know the three likely reasons for the slime, you can keep your cat’s water bowl shiny and sanitary. If you use a water fountain instead of a bowl, you will need to be extra diligent to prevent slime from developing because it contains more parts than a simple bowl. Slime in your cat’s bowl can be a source of dangerous bacteria, so be proactive in fighting back.

I have the hepper stainless steel water bowl for my cat. I clean it regularly, changing the filters more often than recommended due to the slime. I also use natural spring water in her bowl. the slime just keeps showing up. I have done erything suggested above and there is the slime withing 2-3 day of cleaning the bowl and changing filters. any other reason for slime so quickly or suggestions to minimize or eliminate the slime?
That slime is biofilm — bacteria fed by the minerals in spring water and seeded by your cats’ saliva, especially inside the pump and plastic parts.
We recommend switching to filtered or boiled-then-cooled tap water, and give the pump a weekly vinegar soak + scrub to break it down. Hopefully this helps!
