Are you sure we don't own a "scaredy" cat? (Part 3)

Riggs continues to show patterns of being more of a cat than a dog.  First he hates the water, second he sheds a ton and now third he is scared of anything that is out of place or he has never seen before.  Oh no look out for that big green mean trash can on the side of the road.  Protect me for that pillow sitting in the corner of the room.  Yikes! What is that but a wind chime in the tree.  What to do with you, I just do not know.
