Were you doing some blood trailing early this morning?
The paw print looks like that of a dog (probably domestic based on how wide spread the fingers are.) And the blueish/whiteish stuff looks like the the florescent dye that they spray on blood to make it really visible.
Analogy, it is often said the simplest solution is most often correct. You, sir, are correct. Specifically, it’s a puddle of water that had collect in a patch of eroded cement on my patio. I took the picture on a whim and thought it looked really cool, like a shot from the Hubble telescope or something and I really wanted to show it off. Oh and the prize? You are allowed to touch yourself for 2 minutes 😈
