The reasons why cats dig at the water bowl:

1. The cat may dig at the water bowl because he is playing in the water. Some cats like to play in water, especially when they are bored.

2. Sometimes cats cannot determine whether there is water in the water bowl with the naked eye, or if they want to test the level of the water surface, they will put their paws in to test so that they can drink water easily.

3. Some cats like to dip their paws in water to drink. This is a matter of cats’ habits.

4. Most cats have mysophobia, so when they feel that the bowl of water is unclean, they will also want to dig out the water in it.

5. Some insecure cats like to hide water bowls. This is actually an instinctive behavior of cats. The cat will pat its water bowl and push it to where it thinks it is safe.

6. If cats can’t tell whether there is water in the bowl with their naked eyes, they have to use their paws to detect it.
