Lottie Venne was a British comedian, actress and singer of the Victorian and Edwardian eras, who enjoyed a theatre career spanning five decades. Venne began her stage career in musical burlesque before moving into farce and comedy. She appeared in several works by each of F. C. Burnand and W. S. Gilbert and was often in plays with Charles Hawtrey later in her career.

The Zoo is a one-act comic opera, with music by Arthur Sullivan and a libretto by B. C. Stephenson, writing under the pen name of Bolton Rowe. It premiered on 5 June 1875 at the St. James's Theatre in London, concluding its run five weeks later, on 10 July 1875, at the Haymarket Theatre. There were brief revivals in late 1875, and again in 1879, before the opera was shelved.
