What kind of cat is this?

I got this cat as a kitten at the pound. When I got him i didn’t realize how hyperactive he would become. What the video of him playing FETCH! and look at his markings. He isn’t a normal tabby cat. He has a fluffy tail and likes water (or at least will stick his paws in water or go outside during light rain)

I am trying to figure out what kind of “breed” he is. or some possible genetic background.

Here is a video of Benvolio.
