Katnip, the mean Kat, is chasing a group of nice little mice, who are playing and having fun in a toy shop, until Herman, the good mouse,appears in the uniform of a sergeant in the U. S. Army, who has come home on a furlough. Because Katnip has had military training, Herman puts him through a few military exercises, and eliminate the chance that Katnip will be in shape to bother the little mice when Herman's furlough is over.
