Watch the Pittsburgh zoo's baby tigers play with pumpkins on their birthday

Question: What's more adorable than a tiger celebrating its first birthday?

Answer: Two tigers celebrating their first birthday.

With pumpkins.

Pittsburgh Zoo and PPG Aquarium posted a video on Twitter of sibling tiger cubs Andre and Tesha getting their first taste of pumpkin Tuesday in celebration of their first birthday.

The Amur tiger brother and sister can be seen lugging around the pumpkins before eventually settling in to gnaw on them. Yum.

The cubs were born Sept. 25, 2017, and were rejected by their mother , Tierney, zoo officials said late last year at the cubs' public debut. Staff members stepped in and raised the cubs by hand.

They were put into the zoo's outdoor tiger exhibit in May.

Amur tigers are endangered and teetered on the brink of extinction in the 1940s, with only about 40 wild tigers remaining at one point, according to the World Wildlife Foundation. Conservation efforts have boosted the number of Amur tigers in the wild to about 540.
