Kids Free Month at the San Diego Zoo Safari Park will be extra special this year, after the birth of not one, but six endangered Grevy’s zebra foals—adding to San Diego Zoo Global’s ongoing effort to help preserve a population that is in steep decline.

On Aug. 6, 2020, the world’s first successfully cloned Przewalski’s horse was born in Texas at the veterinary facility of a ViaGen Equine collaborator, Timber Creek Veterinary. The foal, born to a domestic surrogate mother, is a clone of a male Przewalski’s horse whose DNA was cryopreserved 40 years ago at the San Diego Zoo Global (SDZG) Frozen Zoo®.
