Anybody know how to replace a wp page with a non wp page?

I want to replace the wp page domain.com/cats with a non wp page named the exact same thing, domain.com/cats. Of course I also want the entire wordpress page to remain live while this page is displayed.

Any ideas? Editing wp files maybe? Easy option?

you need to create your new page as a wordpress template. Then go to the post and assign that post the new template.
You can go html/php crazy. If you want to switch it back you can just assign the post your old wp template again.

The simple option that I can see is adding new page and naming it /cats-1, then when you're done with wp - just rename it.
