Why Hydration is Important for Cats?

Cats need to drink water for both health and sickness. Promoting water intake is especially important for cats who have decreased water intake, increased water losses, or conditions like feline lower urinary tract disease. However, because cats are frequently seen as "poor drinkers," it can be difficult to increase their water intake when necessary. That's where water fountains come in.

How Much Water Should My Cat Drink?

Normally, cats need to drink roughly 4 ounces of water for every 5 pounds of normal body weight each day. However, if your cat eats wet food, they may get a significant portion of their daily water intake from their food. Wet cat food is typically about 70-80% water. So, cats on a wet food diet may drink less than this amount, while cats on a dry food diet will need more.

Why Do I Change My Cat's Water Bowl?

Water is more than just a necessity for survival; it forms a vital part of a cat's daily routine and impacts its overall health. A significant concern for cat owners is understanding that the freshness of water critically affects a cat's water consumption.

This can be attributed to cats' unique and discerning characteristics:

  • Cats and their preferences: Cats are known to be particular about the taste, smell, and appearance of their water. They would rather avoid drinking than consume from a source they deem unfit. This sensitivity can lead to decreased water intake if the water in their bowl isn't fresh and appealing.
  • Bacterial Growth: Stagnant water serves as a fertile breeding ground for bacteria and other harmful pollutants, which can pose serious health risks for your feline friend. If left unchecked, these contaminants can lead to health problems such as gastrointestinal issues or more severe conditions.
  • Sensory Discomfort: Cats have a highly developed sense of smell, making them susceptible to changes in their environment. They can detect any subtle alterations, including any in their water bowls. Accumulated debris or unpleasant odors from stale water can be off-putting, discouraging them from drinking.

Given these points, it becomes evident that maintaining the cleanliness and freshness of your cat's water is not just a recommendation but a necessity. By taking these considerations into account and acting upon them, you can contribute to healthier hydration habits in your cat, and in turn, to a healthier and happier pet.

The Risks of Neglecting to Change the Water Bowl

Neglecting to change your cat's water bowl can lead to a myriad of issues, including:

  • Reduced Water Intake: Cats may refuse to drink stale or contaminated water, which can lead to a reduced water intake and potential dehydration. Dehydration, especially if chronic, can affect many bodily functions and lead to serious health issues.
  • Urinary Health Risks: Chronic dehydration can cause concentrated urine, which can contribute to urinary health issues such as urinary tract infections and kidney stones, both of which are prevalent in cats.

To prevent these potential issues, it's important to regularly change the water in your cat's bowl, ensuring it's fresh and appealing to drink.

How Often Should I Wash the Cat's Bowl?

The frequency of washing your cat's bowl largely depends on the material of the bowl and your cat's eating habits. However, as a general rule, it is advisable to wash your cat's water bowl daily.

  • Daily Cleaning: Ideally, you should wash your cat's water bowl every day with hot, soapy water, then rinse and dry it thoroughly before refilling it with fresh water. Bacteria can quickly build up in the bowl, especially in warm environments, and regular washing helps to keep this in check.
  • Bowl Material: Bowls made from porous materials such as plastic can harbor bacteria more easily. Stainless steel or ceramic bowls are less porous and may be a better choice as they are easier to clean thoroughly.
  • Weekly Deep Clean: In addition to daily cleaning, it's a good idea to perform a deep clean of the bowl at least once a week. This could involve using a bleach solution (make sure to rinse thoroughly afterward), or, if the bowl is dishwasher-safe, running it through a high-temperature wash in the dishwasher.

It's also worth noting that some cats don't like the taste of certain types of soap. If you notice your cat is drinking less after you've washed their bowl, you may want to try using a different type of dish soap.

What About Water Fountains?

Water fountains and filters can be beneficial additions to your cat's hydration system. They provide a continuous flow of water, which not only encourages cats to drink more but also ensures the water stays fresh longer. Despite these advantages, water fountains and filters also require proper maintenance:

  • Fountain Cleaning: Fountains should be cleaned regularly, at least every few weeks. This includes taking the fountain apart and cleaning each component to remove any slime or mineral buildup. Always follow the manufacturer's instructions for cleaning to ensure the longevity of the product.
  • Filter Replacement: The filters in the fountain should be replaced regularly, according to the manufacturer's recommendations, usually every 2 to 4 weeks. This helps to ensure that the filter continues to effectively remove impurities and keep the water fresh.
  • Regular Water Changes: Even with a fountain, you should still change the water regularly, ideally daily, to ensure it remains fresh. While the running water does stay fresh longer than stagnant water, it can still become contaminated with food particles, dust, or bacteria.
How Often Should I Change My Cat's Water


Ensuring that your cat has access to fresh, clean water is an essential aspect of responsible pet ownership. The frequency of water changes, the cleanliness of their water source, and even the specific type of water bowl or fountain can significantly influence a cat's water consumption.

Remember, a well-hydrated cat is typically a healthy cat. Cats can be prone to kidney and urinary tract issues, so adequate water intake is crucial for their overall health and longevity. Regularly changing and cleaning their water bowl or fountain can prevent bacterial growth, promote increased water intake, and contribute to your cat's overall well-being.

Consider the environment, your cat's specific preferences, and any advice from your veterinarian when deciding how often to change your cat's water and clean their bowl or fountain. Always stay attuned to any changes in your cat's drinking habits, as this could be a sign of potential health issues.Ultimately, providing a clean, fresh water source contributes significantly to your cat's health, happiness, and quality of life.
