Cat, your Eastern Boxies, Terrapene carolina carolina (common Eastern box turtle), cover the largest area, living from Michigan and Maine in the north, and range south to the boundaries of the other subspecies.
Mine is an Ornate.
There aren't many things that can prey upon box turtles, but I'd guess it was a raccoon.
