Oil Dripping down my Master bathroom Mirror

This is a video of Oil dripping down my mirror in my Master Bathroom.

When I first saw it, I whipped it away thinking my cat shook after getting water and made a mess. However it was only a few streams and was not anywhere else, I did not think anything about it at first, but when I walked back in the bathroom to put my towels up from doing laundry, their it was again... so I whipped it away again. Fifteen minutes or so I had to use the facilities and it was back again so I decided I think God wanted me to take notice so I did and I recorded it...
