A northern name for a he cat, there commonly called Gilbert. As melancholy as a gib cat; as melancholy as a he cat who has been caterwauling, whence they always return scratched, hungry, and out of spirits. Aristotle says, Omne animal post coitum est triste; to which an anonymous author has given the following exception, preter gallum gallinaceum, et sucerdotem gratis fornicantem.
