You taste it...No you taste it. HONEY come on out side..does this taste like cat piss to you
The reason I'm going with Fluffy's piss being the problem is that I've got 2 different neighbor's cats that don't stay at home to relieve themselves. Now that said is there any critter prints in the snow?
For that much of a stain if the shock is leaking you'll easily find an oil drip at the polished rod entry point to the body. Brown paper from a bag is great for detecting oils. Leaves a nice dark mark unlike water or Fluffy's drain port.

 

Hmmm....didn't taste too bad- gotta try again

 

looks like coolant to me. If you are leaking that bad at a steering stabilizer there will be an oily residue on the stabilizer body where the shaft comes out.
