Trama
George has another job in the city. He has to take care of Professor Wiseman's new kitten, Lucky for a day. Lucky appears to have a crush on Hundley, which is unfortunate because Hundley is allergic to cats. When the Doorman tells George to keep Lucky away, he decides to build a version of Hundley which will not make Lucky sneeze. When things do not work out, George decides to use something of Hundley's, making him mad. When Lucky hears Hundley barking through the air vent, she goes inside the walls of the apartment to try to find him.
