Save the furry kittens.
Ban assault tennis balls.
Sadly, I wish that I had not raised three of my furry friends to play with the optic green tennis balls as kittens. The black walnut tree beside the driveway produces something similar in appearance and led to the death of those three when they chased a green walnut down the driveway and out into the street. Someday, I hope KC and BC and Addie can forgive me for my stupidity.
