Odd Birds & Fat Cats (An Urban Bestiary) is an illustrated collection of brief observations on city creatures. Inspired by the tradition of the medieval bestiary, bestiarum vocabulum, a 12th-century bestselling genre that chronicled animals and beings both real and fantastical, the book features pithy impressions of birds and animals that delight, confound, and edify, written by Peter Wortsman, coupled with detailed naturalist artwork by his daughter, Aurélie Bernard Wortsman.
