Theater, Theater der Vorhang geht auf

The title is from a German song called Theater with text written by Bernd Meinunger.
A section of the chorus translates roughly into:
Theater, theater
the curtain goes up,
then the stage becomes the world.

This describes one of my cats; as can be seen in the photo, she parts and peaks through the curtains ready for action and to have the limelight all on her:)
