Jill preferred the Lion House - the great males arrogant and sure of themselves even in captivity - the placid motherliness of the big females, the lordly beauty of Bengal tigers with jungle staring out of their eyes, the little leopards - swift and deadly, the reek of musk that airconditioners could not purge.  Mike usually shared her tastes for other exhibits, too; he would spend hours in the Aviary, or the Reptile House, or in watching seals - once he had told her that, if one had to be hatched on this planet to be a sea lion would be of greatest goodness.
