Regardless of the age and the breed. Some cats love water, and unfortunately there isn't much to do except use a sturdy, heavy bowl so she doesn't knock it over. For the little paws who dip in the water, put a large napkin on the floor underneath the bowl so that your cat wipes his paws a little when he steps on it.
Telling him off is not the right thing to do, a cat needs to drink and won't understand why he's being told off for playing with water, he will think that he is not allowed to go so that's not good ...
Don't worry growing up he will play a little less with water, but I'm afraid his love for water will last a lifetime.
I had 2 Maine coons who loved water (very common with Maine Coons), when they were 5 years old, they played a little less with water, but as soon as the sunny days and the temperature was rising they would give their little paws baths. They would find any spot where there is water (including toilets), because they needed to cool down. As a result, we had set up "water spots" in our house and would make it fun for them. We would use the bathtub with floating toys or a basin in the garden. It was fun!
