I borrowed this photo, but we have a guy (or gal) like this otter in our pond. Don't think we have any catfish, but who knows. Our renovated pond has been full now for one year, so we should not be surprised that "Spooky"Otter has returned. Or maybe this is a new visitor.
I have named the otter "Spooky," since both Flip and I are spooked out by this animal that spends a lot of time trolling our waters.
This animal is so long, that it is our Loch Wetcreek Monster!
