"Youth" is a science fiction short story by Isaac Asimov.
The story follows the adventures of two young boys (Red and Slim) who find some very unusual new pets in the estate.
The animals seem intelligent enough, and Red recruits Slim to help him train the odd creatures to do circus tricks. But the boys are about to discover their playthings aren’t exactly animals—and they’ve allowed themselves to be caught for a reason...
Youth is a riveting tale from the author of countless classics, including I, Robot and the Foundation Trilogy, which won the Hugo Award for Best All-Time Series.
