All living beings need water. Water means life. Without this amazing liquid, none of us would be here, and a cat is no exception. Cats are made out of 60% water and, even if they don't like to swim, they need a lot of it to stay healthy. A cat water fountain will always make sure that your pet has water available at all times.

Key Facts

  • You need to change the filter of your cat's water fountain every so often. Make sure to read the instructions that come with the product to decide how often you will need to do this. This way, the water will always be clean and pure. We know that you want the best for your cat.
  • If your cat eats a lot of dry cat food, you want to make sure it stays hydrated. Normal water bowls are not enough as the water runs out quickly and it also stays stagnate all day, which is not as appealing to cats as running water. A cat water fountain will act almost as a toy and get your cat to naturally drink more water.
  • Keep in mind that if you have more than one cat, you will need a bigger fountain or more than one normal-sized fountain.

How do cat water fountains work exactly?

There are many different types of cat water fountains. However, they almost always work the same way. They all have the same parts: a pump, filter, and diffuser. Please note that some models may come with extra parts. We will expand on these three common parts below:

  • Water pump: This part of the cat fountain is vital as it helps circulate the water throughout the entire system. Depending on the model that you purchase, you may be able to change how the pump works, as a certain water flow may attract your cat more than another. This requires electricity, but don't worry. It consumes very little energy.
  • Filter: This part is key to providing your cat with fresh, drinkable water. Its purpose is to clean the water before it gets to your cat. Many filters in cat water fountains use activated carbon, which is also used in products for humans. Different fountains have different types of filters.
  • Diffuser: The diffuser dispenses the water. This is the part that changes the most depending on the model you purchase. There are many options: soft streams of water, waterfalls, bubbles, or constant flow. You should choose a fountain with a diffuser that you think will entertain your cat the most. You know your pet best.

Are there cordless cat water fountains?

Yes, there are cordless fountains on the market. These are usually called automatic cat water fountains. They have a sensor that will automatically dispense water when your cat is close. This way, you will save more energy.

What materials can cat water fountains be made out of?

Just like any product, it is important to note what material your cat water fountain is made out of. Most of these items are mainly made out of plastic but keep in mind that these products are usually made of more than one material. Below, we will discuss the different materials found in cat water fountains:

  • Plastic: The best options are usually made out of high-quality plastic. This material is sturdy, inexpensive, and lasts a long time. However, you will have to clean this type of fountain more often, as plastic usually cracks and creates room for bacteria growth.
  • Stainless steel: This material stands out because it is very lightweight. However, it is not as sturdy as plastic. This material will not crack as easily as plastic and is hypoallergenic. Cat water fountains made out of this have smaller capacities (between 0.5 to 1 gallon). This avoids the water from becoming smelly.
  • Ceramics: The models that are made out of ceramics are very sturdy and can last you for a long time. They have thermal properties and keep the water at a good temperature. This type of fountain is also very easy to clean. However, they crack more than plastic and can attract more bacteria. So, you will have to clean them often.
