Boondocks Denizens

When Fiorella took Sonya Dog out for a walk yesterday morning, they came across a dead baby possum lying on the gravel driveway.  Sonya was curious, but obeyed Fiorella's command to "leave it."  The second time around the driveway, the possum was gone.  Was there a mysterious predator in the woods that had carried it off--maybe a fox, like at the White House?

Or had the baby just been . . . playing possum?
