“This book is about a simple, benign experiment, or perhaps we should call it an inquiry, to learn what are the essential ingredients in interspecies friendships and even love. The basic idea was to raise together a kitten, a puppy, a bunny, a chick, and a baby rat in close circumstances to see if they would all get along and even become good friends.”

"The Achievement of the Cat"
The Square Egg (1924)
Context: The animal which the Egyptians worshipped as divine, which the Romans venerated as a symbol of liberty, which Europeans in the ignorant Middle Ages anathematised as an agent of demonology, has displayed to all ages two closely blended characteristics — courage and self-respect. No matter how unfavourable the circumstances, both qualities are always to the fore. Confront a child, a puppy, and a kitten with a sudden danger; the child will turn instinctively for assistance, the puppy will grovel in abject submission to the impending visitation, the kitten will brace its tiny body for a frantic resistance. And disassociate the luxury-loving cat from the atmosphere of social comfort in which it usually contrives to move, and observe it critically under the adverse conditions of civilisation — that civilisation which can impel a man to the degradation of clothing himself in tawdry ribald garments and capering mountebank dances in the streets for the earning of the few coins that keep him on the respectable, or non-criminal, side of society. The cat of the slums and alleys, starved, outcast, harried, still keeps amid the prowlings of its adversity the bold, free, panther-tread with which it paced of yore the temple courts of Thebes, still displays the self-reliant watchfulness which man has never taught it to lay aside.
