That means Eric's solution fits perfectly well here.

	< system in single state : everyone sees cat = alive >

	insert_into_box(cat);

	< system in dual state : new calls see cat == dead, but
	  current calls see cat == alive >

	open_box();

	< system is back to single state: everyone sees cat = dead >

	funeral(cat); 

no problem ;-)
