Run Rabbit Run

This is a quick little drawing of an image that has been percolating in my mind for quite some time.  I have been wanting to create this scene of a cat family posed portrait with puppets but haven't quite figured out how yet.  So why not draw it?  The original idea was to have a mother and two daughters, but for this one we have the classic mother, father, older sister and younger brother, who is definitely not happy to be there.  The girl is though.  She's a darling angel.  Her parents must be proud.
Why does only the mother have whiskers?  I don't know.  Maybe the children are too young and the father shaved his off.
