I was eating mini marshmallows today, and I dropped one. My cat, being the vicious beast that he is, pounced on it, "killed" it, and ate it. Apparently he liked it, because I left the bag on the table when I went to class this evening, and came home to find it open and substantially emptier than it had been.
I only hope that a quarter bag of marshmallows doesn't cause feline digestive problems.
