Cats have a natural aversion to water, which is likely due to their ancestors' habitat in dry environments.
Cats are also meticulous groomers, and their fur can become heavy and matted when wet, making it difficult for them to clean themselves.
Some cats may have had negative experiences with water, such as being sprayed with a hose or accidentally falling into a pool.
Cats may also dislike the sensation of water on their skin, which can be uncomfortable or even painful for them.
The sound of running water can also be stressful for cats, as it may remind them of predators or other dangers.
However, not all cats hate water - some breeds, such as the Turkish Van, actually enjoy swimming and playing in water.
If you need to bathe your cat, it's important to do so gently and gradually, using lukewarm water and a mild shampoo.
You can also try using a damp cloth or waterless shampoo to clean your cat's fur without getting them wet.
