All the books I've read whose titles include the names of non-human, non-mythical living creatures - even if they weren't intended that way! If anyone's interested, there are 462 animals (some titles contain more than one). Most common: horses (33), rabbits (26), cats (22), dogs (20), wolves (18), mice (17), elephants (15). Commonest birds: eagle, goose, lark, swan (9 each). 35 raptors, 9 corvids. 17 assorted insects.
