Disney’s Animal Kingdom has announced the Sumatran cubs born last month are a boy and girl and are weighing in at 12 pounds each.

The cubs are learning to walk and bonding with their mom, Sohni, who has been feeding and grooming the twins throughout the day, according to the Disney Parks blog.

The tigers were bred through the Species Survival Plan, which is overseen by the Association of Zoos & Aquariums and ensures responsible breeding and diverse populations of threatened and endangered species. Sumatran tigers are critically endangered, with fewer than 500 existing in the wild due to significant threats like habitat loss, poaching and the illegal wildlife trade.

Sohni and the cubs’ father, Malosi, were brought to the theme park in 2014 to expand its breeding program.

Guests can support Disney’s efforts to reverse the decline of tigers and other animals by taking part in Connect to Protect, a mobile adventure in conservation missions with a digital scientist while exploring Pandora – The World of Avatar.

After completing one or more missions, the app will unlock a $10 contribution from Disney Parks, through the Disney Conservation Fund, or a $5 contribution just for discussing conservation. Participants can choose how the contribution will help protect or restore habitats important to one of 10 threatened categories of animals: apes, elephants, butterflies, coral reefs, cranes, monkeys, rhinos, sea turtles, sharks & rays, and tigers.

The tiger cubs will remain backstage for the next few months before guests can see them on Maharajah Jungle Trek.
