A two-and-a-half-year-old chimpanzee called Dodo has been trained to feed tiger cubs out of a bottle.
He's been feeding the cubs every day for more than a year at the Samut Prakarn Crocodile Farm and Zoo in Thailand.
Dodo's trainers say that he wasn't afraid of the tiger cubs, so they taught him how to feed them.
But sometimes he ignores his feeding tasks, and just wants to play!
"He just fed the cub but he also teased the tiger by taking away the milk bottle," said 10-year-old Raksika Chueawong, who visited the zoo.
Zoo workers say tourists love taking pictures of Dodo and the cubs, but they'll have to be separated soon when the cubs get too big.
