Frog Death Investigation

 This morning I was presented with a rather sad sight.  When I went out to feed the Goldfish, I noticed a frog floating on the surface.  Sometimes they do that and finally swim away as I approach but this one didn't move.  I scooped him with the net and noticed some yellow innards sticking out of his left side.  When I turned him over, there was a blob of brown innards sticking out.  I remembered we disturbed a large owl last night near the pond so I wonder if the owl had attached this little guy but flew away without his treasure as we approached.  I don't know for sure but something attacked and left in a hurry.
