'Audrey Style' by Pamela Clarke Keogh (Aurum Press, 1999)
'Audrey Hepburn: an elegant spirit' by Sean Hepburn Ferrar (Sidgwick and Jackson, 2003)
Fortunately you don't seem a judgmental person, therefore you won't think my Venus rather conventional, being more of a donkey/deer/dog person yourself.
Once, when she was still an unknown cabaret actress and dancer, Audrey adopted a stray cat and called it Tomorrow.
(From 'Audrey Hepburn', by Barry Paris, Orion Books 1996)
