Sumatran Tiger / San Francisco Zoo

This Sumatran Tiger cub, born at the San Francisco Zoo on 10 February to mother Leanne, has had its first vet check this week and it was determined that it’s a girl. To minimally interrupt mother-cub bonding, the exam was done in less than 5 minutes, revealing that the five-week-old is in excellent health and thriving under her mother’s care. And since this is a solo cub and there is no competition for milk, the baby has a nice big belly and weighed in at 8 pounds. Her next exam will take place around 10 April, when she is 8 weeks old — via ZooBorns
