Well, I Suppose It’s Possible

 We were hiking through the forest when we came to a half eaten bird carcass.  It wasn't particularly alarming because Brutus the cat brings us a lot of special dead animal love gifts and deposits them right out the back door where we are sure to see them.  After looking carefully at the medium sized bird remains, we did a little brainstorming about what might have caught the bird and lunched on it:  a fox, a racoon, maybe even a cat.  

"Oh!  Oh!  Mom! I know!  I have an idea!"  exclaimed a very excited boy.  "I bet it was a desperate walking plant with big green teeth!"
