The reason why cats often paddle with their hands when drinking water may be because they are unsure of the water level, like fluctuating water, or are afraid that their whiskers will touch the water bowl. This is a normal phenomenon, and many cats will exhibit this behavior before drinking water. The owner does not need to worry too much.
Tips:
If the cat often scratches the water with his hands when drinking water, it is best to change the water for the cat to a larger one. A bowl or an automatic water dispenser. At the same time, pay attention to the hygiene of the water bowl to avoid the growth of bacteria.
