You must have a deep pan of PDZ?
I use thin layer and yes, juicy poops will freeze and stick, and yes they can go flying but never into my face.
It's 1/2" thick and runny poop will still freeze to the bottom sometimes. I just leave that until it thaws.
I use a round rake so no matter what angle the handle is the dept remains the same and you can get right into corners with it.
