How to Prevent Slime in Pet Water Fountain?

How to prevent slime in pet water fountain

How to prevent slime in pet water fountain is a question you may want to address seriously.

Slime in your pet’s water bowl and pet fountain is basically bacteria that bonds together to form a slippery film (called biofilm) on the surface.

At worst, it can make your dogs and cats really sick and at best, it can cause tear stains, watery eyes, dental caries, and upset tummies in your pets.

Slime in your pet’s water bowl and food bowl even has the potential to make you sick when you pick up and accidentally touch it.

In this guide, we will tell you ways to prevent slime in pet water fountains.

We will also review some cat water fountain that doesn’t get slimy because of their non-porous materials and continuous flowing streams.

What is Slime on Pet Water Fountains?

Slime is the formation of a biofilm that consists of colonies of bacteria and other microbes that cling firmly to the surface of your pet’s water bowls or water fountains.

The joining of these microbes forms a slimy layer that sticks to your dog and cat fountain surfaces.

Biofilms are not limited to pet water bowls or fountains alone. They are found pretty much anywhere where you have moisture with a suitable surface.

Pet water fountains provide a favorable place for harborage of bacterial colonies because of their tubing, pipes, and small parts that escape cleaning.

Your pet’s drool and saliva contribute to these colonies of bacteria (both good and bad) and are responsible for the pet fountain slime on your pet’s water fountain.

The pink residue slime contains bacteria, fungi, protozoa, and algae which can lead to tummy upsets, tear stains, dental issues, and digestive troubles like vomiting and diarrhea in your pets.

Even humans can indirectly get sick due to this slime when they accidentally touch it while picking up the bowls or cleaning the fountains.

How to Prevent Slime in Pet Water Fountain?

Thankfully, it is not too difficult to prevent slime in pet water fountains. Here are some ways to deter slime formation:

1) Change the Water Regularly

The easiest way to prevent slime in pet water fountain is to replace the reservoir of your pet fountain with clean water regularly, even if your pet does not finish all the water in the fountain.

When we say regularly, we mean at least once every other day. And of course, the best practice is to replace the water once every day.

Some fountains come with an indicator light to alert you when the reservoir is empty however, by the time you are alerted to change the water, too many days may have lapsed and slime may have started to grow on your pet fountain.

Remember, the main goal of this is to remove water that is stained with your pet’s saliva and bacteria growth and to replace it with fresh water.

Spending 1 minute daily (or every other day) to replace the water can help prevent slime buildup as well as ensure the wellbeing of your pet! Isn’t it time well spent!?

2) Place Your Water Fountain Away From Heat and Light Sources

If you are already replacing your pet water fountain daily (or every other day) with fresh water, and you still find slime buildup in your fountain, then check to make sure that your pet’s water fountain is placed away from heat and light sources (especially away from direct sunlight).

This is because warmth encourages growth of bacterial colonies and also leads to formation of algae.

The best practice is to place your pet water fountain in a cool dry place accessible for your pet and away from any heat and light sources.

3) Clean Your Pet Water Fountain Regularly

Regular cleaning (as described below) can help prevent slime formation.

Even though you are already replacing your pet water fountain with fresh water daily, bacteria can still buildup in obscure places such as in the tubings or the inner parts of your fountain.

Therefore, having a regular cleaning routing for your cat and dog water fountain is equally important to eliminate pink residue slime buildup.

You can use vinegar, baking soda, bleach, or mild detergent to clean the different parts of the fountain.

Once in a while, sanitize the fountain parts with hot water to kill germs and slime-causing bacteria.

4) Use Ceramic, Stainless-steel or Porcelain Fountains

Last but not least, if you have tried the above 4 steps and you still find considerable slime buildup in your pet water fountain, then you can consider to purchase a dog and cat water fountain that doesn’t get slimy.

They are made with high-quality materials like BPA-free plastic, stainless steel tops and spouts, porcelain, or ceramic materials that naturally discourage slime formation.

Many vets recommend glass, porcelain, ceramic, and steel food bowls and water fountains because they are less porous than plastic which prevents bacterial accumulation.

These materials are also easy to clean and do not require heavy-duty scrubbing.

Avoid fountains with cheap materials that scratch and abrade easily providing bacterial colonies plenty of hiding places that lead to slime formation.

Why Does My Pet’s Water Fountain Get So Slimy?

Now that you know the answer to the question ‘how to prevent slime in pet water fountain?’, let’s also take a closer look at the causes behind slime.

1.  Stagnant water

Water fountains have a tubing to let the water flow up through it when your pets drink water from its nozzle.

However, this water is not always flowing and intermittent stagnation occurs inside the tubing, overnight, and when your pets do not use the fountain.

This causes planktonic community of bacteria to attach to the walls of the fountain’s tubes.

2. Pet drool and saliva

If your pet happens to drink water from the pet fountain right after eating kibble, its saliva can drop into the fountain and feed the bacterial colonies to further their growth.

This feeds the planktonic colonies that contribute to further bacterial colonization.

As a result, pet owners might see pink slime in pet water fountain.

This pinkish slime consists of S.marcescens bacterium that is also found in bathtubs and kitchen and bathroom sinks because it thrives in places where there is moisture.

3. Sunlight

Some units are also heated to provide warm water and prevent icicles in the water.

Heating the water further enhances the growth of microorganisms.

Some people erroneously place pet fountains in sunlight which further encourages growth of algae and slime.

Water fountains sometimes have a complex maze of waterlines which allow water to accumulate in them leading to biofilm formation.

4. Water in your area

Municipal water supply in some areas also contains planktonic bacteria which can contribute to slime formation in pet water fountains.

What are some of the Diseases Pets can get from Slime in Pet Water Fountains?

A pet fountain looks attractive and is a great way to ensure that your pet drinks adequate quantity of fresh and healthy water.

However, this seemingly innocent looking fountain is a breeding ground for many pathogens.

A) S.marcescens bacterium

The S.marcescens bacterium found in the pink residue slime on water bowls can cause skin issues, meningitis, and other serious infections.

Slime is especially known to promote periodontal diseases in pets.

B)  Salmonella and e.coli bacteria

Sometimes, slime can also contain salmonella and e.coli bacteria which can cause gastrointestinal problems like severe vomiting and diarrhea, urine infections, meningitis, blood infections, and other diseases in weak and immunocompromised pets.

C) Harmful to weak/sick/immunocompromised pets and humans

Healthy pets may not always get sick from slime.

However, slime can harm weak and sick pets and humans – children and elderly people – when they accidentally touch the slime in the water fountains.

How to Get Rid of Slime in Pet Water Fountains?

Pet water fountains are a great way to ensure that your pet gets to drink clean and fresh water daily.

Cleanliness and maintenance of pet water fountains does not take any more than 15 minutes at a time.

Most manufacturers recommend cleaning the fountain once in 2 weeks.

1) Wash The Parts in the dishwasher

Good-quality water fountains come with easy-to-separate parts that you can wash in the dishwasher.

Run the regular cycle for a squeaky clean fountain that is free from that disgusting pink slime.

2) Use Vinegar & Baking Soda

You can soak the parts (bowls, lids, filters, caps, and spouts) in warm water mixed with some vinegar.

Soak them for at least 10-15 minutes. This will kill the bacteria and microbes. Rinse the parts thoroughly under running water.

If your pet water fountain has tough algae buildup, you can also sprinkle some baking soda after soaking in vingar to effectively remove the deposit.

For pump-based fountains, you can run a cycle of water and vinegar to clear off any accumulated slime in the fountain pump and tubing.

3) Use detergent or bleach

You can also wash the fountain parts in warm water with some mild dishwashing detergent or bleach.

If needed, scrub the accumulated slime with a plastic or metal scrub (as instructed by the manufacturer). Rinse thoroughly.

How Often Should You Clean Pet Water Fountains?

Most pet water fountain manufacturers recommend deep-cleaning the fountain once every 15 days.

You must also change and replace the filter every month or as recommended by the manufacturer.

How Often Should You Change The Water In A Pet Fountain?

Changing the water in your pet water fountain is definitely one sure way to prevent slime formation.

Although there is no hard and fast rules about this, we recommend you to change the water at least once every other day to keep your pet’s drinking water fresh and also to remove any bacteria and food particles in the water.

What Type Of Water Will Prevent Pet Fountain Slime Best?

Unfortunately, pet fountain slime can happen no matter what type of water you use. There is no evidence that using a certain type of water can prevent pet fountain slime.

Pet fountain slime is formed when bacteria feeds on the organic matter that is introduced into your pet fountain’s water.

The organic matter comes from your pet’s saliva or food particles from your pet’s mouth.

The best way to prevent pet water fountain slime is to wash it regularly and thoroughly.

Frequently Asked Questions

1. How does saliva contribute to pet fountain slime?

Every time your pet drinks from it’s water fountain, it’s tongue will come into contact with the water and inevitably introduce saliva into the water.

Your pet’s saliva is a reservoir of food particles, microscopic simple sugars (food particles that is broken down by saliva) and bacteria. All of these get introduced into the pet fountain water whenever your pet drinks water.

Pet fountain slime gets formed when bacteria feeds on the food particles or simple sugars.

These bacteria can either come from the air inside our home or from your pet’s saliva.

2. Are Plastic Pet Water Fountains Safe?

There are some concerns about plastic pet food bowls and water fountains causing contact dermatitis and acne in pets, especially in cats.

 Some cats developed chin acne while a few got swollen lips due to plastic food and water bowls.

However, top-quality BPA-free plastic fountains are generally safe and majority of the pets had no issues with it.

It also depends on how regularly you clean the fountains.

The common cause behind canine and feline acne is bacteria in the unclean surfaces of bowls. So, if you regularly clean your pet water fountains, there should be no cause for concern about this issue.

Having said that, it is always a good idea to talk to your vet and check if plastic water fountains are right for your pets.

You can also choose ceramic, stainless steel, and/or porcelain pet fountains which naturally resist slime formation and are also easier to clean owing to their non-porous surfaces.

3. How to clean a plastic cat fountain?

The first step is to disassemble all the parts of your plastic cat fountain including the tubes connecting to the fountain pump.

As water and bacteria can stagnate within any parts of your cat fountain, it is very important to wash all the parts.

If you are not familiar with cleaning your cat plastic fountain or if this is your first time, we suggest you to take note of the connecting parts of the fountain so that you will be able to put them back after washing.

Next step will be to wash all the parts. You can either place them in your dishwasher (but first make sure they are dishwasher safe) or you can wash them manually with a brush and soap.

If you are worried about pet water fountain slime, you can also soak your plastic cat fountain in vinegar to remove the lurking bacteria stuck on the pink residue slime.

Soak the pet fountain parts (bowls, lids, filters, caps, and spouts) in warm water mixed with some vinegar for at least 10 – 15 minutes. Then, rinse them thoroughly under running water.
