Had two otters in one trap 7 times over the years.And two otters on a snarepole once. A few mink and rat in one trap,in those cases the mink was already dragging the rat Have had two squirrells in one trap a few times and a weasel and squirrel in one trap a few times.
Can't be all that rare with otters since it has happened to me. I hear about it fairly often. Cool when it happened when the prices were over $100.00 each as was my situation.
Seems that way, were HUGE carp scales in their scat when i was up in Mo. working. No idea why they want to take on a 40 lb. carp instead of a hand sized blue gill or such.
