Raccoon.
So I let Romey out the back door tonight and wandered out behind her to see what she was doing. Luckily for her she decided to take off in a mad dash up the grass. Just then I thought that I saw a cat walking on the patio. However, this cat had a striped tail. By the time I realized that we had a Raccoon in the yard, Romey was freaking out behind a fence. The Raccoon stayed ultra calm and just watched and then decided to climb a fence into the neighbors yard. Could Romey have taken this wild animal? Luckily I didn't have to find out.
