Why Do Cats Drink Dirty Water From Puddles and Ponds?

Why do cats drink dirty water? Our cat likes drinking from the fish pond. Is it dirty? Well to me it is but kitty might have other ideas.

The filter in the pond isn’t always turned on and the water can be murky in appearance.  The cat will also drink from a ceramic pot that is near the fish pond. The pot is empty and doubles as a water dish, regularly filling with water from the reticulation for the garden.

As the cat has become older he is more likely to drink the clean water in his water bowl inside the house. This is a fairly recent move, he is 17 and getting to and from the fishpond takes more effort.

FAQ About Cats Drinking Water

1. Location - Water Bowl

Often the reason that a cat will seek out water other than the nice fresh water you have supplied, is because of the location of the water bowl.

As humans we may think we are doing kitty a favor by putting the food bowl and the water bowl side by side thinking it will be convenient for kitty.

However, if the water bowl is too close to the food, the cat will instinctively feel that the water could be contaminated.  This is because in the wild a cat would never drink water that is near freshly killed prey in case the water is contaminated. He has forgotten that his can of Purina isn't freshly killed prey.

Choose a different location for the water bowl. Make sure that it is not too close to the food bowl. To make it easier for you to empty, clean and refill the bowl, the best option will be to choose a place that is close to a water supply.

2.  Fresh Water


Even the water in the toilet can be fresher than the water in your cat’s bowl. To us it isn’t, however the water in a cat’s bowl can quickly become stagnant and stale and build up a nasty collection of dust and cat hair and other fragments of dirt.


We have all seen YouTube videos or heard of animals that like to lap water from the toilet or a tap running in the kitchen or bathroom sink.  


Some cats will definitely not drink tap water so it may depend on the chemicals contained in the tap water where you live. Tap water can definitely have a chemical taste.


A freshly flushed toilet may seem fresher to some cats cat than the still water sitting in the water bowl. 

3. Temperature 


Just like humans, cats can be picky about the temperature of their drinking water. Some cats love to have ice placed in their water bowl when the weather is hot.  Some cats love to lick the condensation from windows and some cats prefer the warm water in a shower or bath water.


Watch this cat drinking from the fishpond. He is not disturbing the fish he is just drinking.

4. Size And Shape Of The Bowl


When choosing a water dish or cat water fountain, ensure that you are making choices based on what will be the best for your cat.


Sometimes we are are lured by the bright, pretty things but essentially the drinking bowl needs to be practical for your cat.


The size of the bowl/fountain may be uncomfortable for your cat. Some bowls may be too deep or too narrow.


Some cat breeds have a flat face profile.  Flat faced cat breeds can have health problems and may not be able to access water in a deep bowl. The same applies to feeding flat faced cat breeds. If the pretty designer bowl you have is being ignored, it may be because it is not practical to use from the cat’s standpoint.


If you cat finds it awkward to drink, even if the bowl is Michelin star restaurant standard, he make seek other sources.

5. How Does The Water Taste?

How To Encourage The Cat To Drink From A Bowl

1.

Make sure that the water dish is thoroughly washed and rinsed daily.

2.

Cats have a keen sense of smell and a bowl that has not been properly rinsed will still have the scent of detergent and will not be appealing to a cat. 

3.

Your cat may also play with the water in his bowl, swiping with his paws. Those paws may have come straight from the kitty litter, highlighting the need for thorough cleaning.

4.

Try bowls made from different materials. Stainless steel, glass and ceramic are preferable to plastic, however this may take some experimenting.

5.

Think about the depth of the bowl. Can kitty reach the water easily? If the bowl is too deep or the water level too low, kitty will have trouble accessing the water.

6.

Consider a drinking fountain.  Cat water fountains aerate the water to keep it fresh. Cats like the sound of running water and the movement that the water fountain makes.  Some kitties will swipe at the water.
