Two black-footed ferrets at the Smithsonian's National Zoo have each given birth to a kit that was sired by males who died in 1999 and 2000. These endangered ferrets—part of a multi-institutional breeding and reintroduction program—were artificially inseminated in May with frozen semen from the two deceased males, each giving birth to a kit on June 20 and 21 respectively.
