Have you ever wondered why cats can’t swim? It may surprise some pet owners, but cats are the only domesticated animals that cannot swim. This is because they don’t have the same natural ability as most other animals or humans. But why is this? Let’s dive into the science behind why cats can’t swim.


Why can’t cats swim?


Cats are not naturally strong swimmers due to a few factors.

  • Firstly, cats have dense bones, making them challenging to float.


  • Secondly, most cats have coats of fur that become waterlogged and add extra weight to the water making it more challenging for them to move around.


  • Lastly, cats do not have webbed paws like other animals, such as fish and ducks, reducing their ability to provide enough propulsion and maneuverability in the water.


In sum, although cats sometimes enjoy paddling, their build does not make them natural swimmers.


Cats Don’t Have Webbed Feet


One of the primary reasons cats can’t swim is that they don’t have webbed feet like most other aquatic animals.

Animals like ducks and beavers typically have webbed feet that help propel them through the water while swimming.

Without these specialized appendages, cats don’t move very well in water.

Additionally, their fur traps air, making it difficult for them to stay afloat and swim through the water instead of merely bobbing along with the currents.


Weight Distribution Matters


Cats also have a higher center of gravity than other mammals that can swim naturally.

That means that when cats enter the water, their heads tend to sink rather quickly due to their heavy chest area being weighed down by gravity.

This makes it difficult for them to remain afloat without using their front paws as paddles to stay afloat continuously.

For this reason, swimming isn’t precisely an instinctive behavior for felines; it’s something they have to learn to do if we want them to.


Density Plays a Role Too


The density of a cat’s body also contributes to its lack of buoyancy in water compared with aquatic species such as otters or seals, whose bodies are comprised mainly of fat and blubber, which helps keep them afloat while they’re in the sea or lake fishing for food.

In contrast, a cat’s body has denser muscle mass and bone structure, which causes it to sink more quickly than those water-loving mammals that evolved specifically for life in an aquatic environment.




It may be a surprise that cats can’t swim—but there is a good reason behind it. Feline anatomy isn’t designed for swimming like many other animals (mainly aquatic ones). Cats lack webbed feet, which means they don’t move very well in water, and their heavier body weight combined with denser muscle mass makes it harder for them to stay afloat without using extra effort from their paws as paddles to remain above sea level.

While cats can be taught how to swim, they aren’t naturally equipped with all the tools necessary for successful hydrodynamics in an aquatic environment like some other species are – so make sure you keep your kitty away from any large bodies of water.
