This book on Cats, the only one by which he is now remembered, was the sole production of his lifetime which cost him any annoyance. He was forty years of age when it appeared, and the subject was considered a little frivolous, even for such a petit conteur as Moncrif. People continued to tease him about it, and the only rough thing he ever did was the result of one such twitting. The poet Roy made an epigram about “cats” and “rats,” in execrable taste, no doubt; this stung our Sylph to such an excess that he waited outside the Palais Royal and beat Roy with a stick when he came out. The poet was, perhaps, not much hurt; at all events, he had the presence of mind to retort, “Patte de velours, patte de velours, Minon-minet!” It was six years after this that Moncrif was elected into the French Academy, and then the shower of epigrams broke out again. He wished to be made historiographer; “Oh, nonsense,” the wits cried, “he must mean historiogriffe” and they invited him, on nights when the Academy met, to climb on to the roof and miau from the chimneypots. He had the weakness to apologise for his charming book, and to withdraw it from circulation. His pastoral tales and heroic ballets, his Zelindors and Zeloides and Erosines, which to us seem utterly vapid and frivolous, never gave him a moment’s uneasiness. His crumpled rose-leaf was the book by which his name lives in literature.
