Opposable thumbs

the back door  Handiwork by Ruby

Ruby doesn’t have opposable thumbs.  Therefore, she is unable to open the screen door from the outside (she can open it from the inside but she uses her nose).  Since she can’t let herself in she has learned that a loud and highly irritating scratching frenzy gets her immediate access to the house.  She refuses to bark because the scratching is so effective.

 

Ruby's at it again!
