Cats originated in arid deserts and have had very little contact with water during their evolution. Therefore, most cats are inherently inexperienced with water and have a deep-seated fear of it. Furthermore, when cats are bathed, their fur becomes completely wet, clinging heavily to their bodies and hindering their agility. Wet fur is extremely uncomfortable for cats and usually takes a long time to dry. Reduced agility makes them easier prey for predators. 
How to get your cat to accept bath time:
1. Get your cat used to bathing. Let your cat get familiar with the bathroom environment beforehand so that it knows that this place is not a threat to it, and it will be relatively docile during the bath.
2. Grooming is something cats enjoy and appreciate, so you can groom it before bathing it to help it relax.
3. It's best to use a tub for bathing. The water level should not be higher than the cat's belly, otherwise the cat will feel insecure. You can put a non-slip mat or the cat's usual small blanket under the cat's feet to increase the cat's sense of security.
