Every day for more than a year, Dodo the chimpanzee has been feeding tiger cubs at Thailand's Samut Prakarn Crocodile Farm and Zoo.

"I taught him how to hold the bottle and stay with the cubs," chimpanzee trainer Sirinaj Nimnoradee explained. "I've been teaching him every day - but sometimes he plays with the cubs too."
