Corral puzzle

The standard form of this puzzle is a grid with numbers in some cells. A single closed loop is to be drawn along the edges of the grid so that all the numbers are inside the loop, and the number of squares in the row and column through each number, going up to the first part of the loop encountered in each direction, and counting the cell with the number once, equals the number. The instructions for Cave have you shade in the cells outside the loop, but with rules which make it functionally the same puzzle.
