Congrats to Lola, a Sumatran Tiger at the Oklahoma City Zoo, who has just given birth to twins. But that's not all, five years ago she had triplets! Just after they were born, she was given a fourth newborn tiger to take care of, an Amur tiger born at the Philadelphia Zoo. Lola's generous act became the very first documented case of cross-fostering tigers of a different subspecies! Currently tigers are critically endangered, so a big thank you to Lola, and to everyone who helps these majestic and precious big cats, no matter which subspecies they belong to.
