Lions 'n' tigers 'n' everything
(1922)
“ In fact, the only thing that can arouse greater excitement among felines than a dog is that outcast of the animal world, the hyena. Here the racial lines are drawn sharply and distinctly; it is an enmity which is at high pitch always; the very proximity of a hyena cage will drive a tiger or leopard to madness, and if a feline is placed in the compartment opposite to a hyena, it seldom ceases its efforts until the day when some careless animal attendant leaves the partition door unclamped, when the feline can claw and tear until it raises the barrier and rushes through to annihilate its foe. ”
