What all are you using on it so far to clean with? Anything helping so far since it has been a few days?

You most likely will have to pull up the floor and possibly the subflooring and replace it all. You can try to paint the floor by using Kilz with an odor sealer (ask them which one to use) and see if that will take care of it first before you go ripping up your floors, but if it is that bad, I'm not sure if you will be that lucky. Good luck to ya.
