After watching the ferret movie - :-) - I was inspired to go out and buy
some hard plastic balls to put in a box.  But all I could find was tennis
balls and ping pong balls.  Ok for a start.
 
Any suggestions of where I might find some nice colourful balls?  (generic
type shops - no chain names - I'm in Melbourne Australia).
 
Princess didn't seemed fussed by the balls, but she did appreciate having
to climb up inside the tube to the box on the bookshelf.
