None of the above. It was a dead mole which we discovered later had the misfortune of burrowing up right in front of the part of the patio where Momo's food dish is located.
As this is the second time she's caught a mole, I'm thinking of making a stencil so we can paint her kills on the side of her dog house.
Momo was a little put out that we took away her "toy". She didn't understand at all.
