Why house cats hate water while wildcats love water?

I know the difference between "feral cat" and "wildcat".
The wildcats I talked about are the true wildcats in the wild. Not the escaped or abandoned domestic cats.

Tiger certainly love water. Not all tigers are from hot places. Siberia tigers for example, come from places with heavy snow in the winter.

Although I was talking about true wildcat species. Many of them will running around in shallow water to catch fish for food. From one of the Savannah cat video, the owner said his cat will jump into water every time they pass a pool of water if he doesn't stop him. It sounds like wildcats love water to me.
