Another Amur tiger cub was born to Toma on May 11, 2008. The male cub, Grom (name meaning Thunder for he was born during a thunderstorm), had been taken from his mother because Toma was not being very attentive to him. Handlers later determined that it is most likely because Toma is not producing enough milk, if any at all. On September 12, 2008, the baby cub was named after Billy Ray Cyrus, the country music and television star. Zoo representatives said the donors who paid to name the cub “Billy Ray” wanted to honor a late family member who was a big Cyrus fan.
