Last year I was on vacation, my sister inlaw came over to use the pool and called me to let me know a skunk was dead floating! YUCK. She is an amazing woman, as she got a shovel and her and my niece fished it out and pitched it into the woods (where it stank for 2 months!).
I had her put the salt cell on super chlorinate .. when I got home I checked an had no CC and all looked good. Monitored daily (realistically hourly) for a while and all was well.
Moral of the story, had a mouse before too, lots of frogs, but the skunk I hope was my worst and hope is the last large animal!!
