Live Trap

This morning I discovered some unidentified animal poop in our back yard.  So this afternoon I went out to the animal shelter where they will let a person borrow a live trap.

So this will be the  "Before" picture.

I'm thinking I'll have the after picture tomorrow.  
I'm not sure of the animal but I do know it's not a cat or a dog.  My best guess is an opossum or a large rat.
Obviously, I'm not looking forward to dealing with whatever ends up in the trap.
