They only heard the animal move around and never saw it .None of the above choices .They never learned the difference between the two animals .They were blind and could only hear the animal scream .
What may be the reason why they thought the bat was a mouse ?
I had a bat once , except I thought he was a mouse , and I named him Fred . I was living in a converted attic outside of Cambridge , MA and my roof was slanted . Someone put a wall from the part of the roof that was too low to walk under to the ground , and some of that I used as closet space , and the rest was storage for the person who owned the house .
