Two-year-old chimpanzee Do Do found a new playmate in 60-day-old tiger cub Aorn at the Samut Prakan Crocodile Farm and Zoo in Bangkok.
The Samut Prakan Crocodile Farm is home to over 80,000 crocodiles and is the largest in Thailand, but the crocs were not the main attraction at the zoo this weekend.
Chimpanzee Do Do wowed onlookers as she playfully fed milk to Aorn - a golden tiger cub.
Do Do, dressed in a pair of blue jeans, let Aorn curl up in her lap as she fed him from a bottle as a parent would to its child.
The pair were inseparable as the chimp looked after young cub Aorn for the afternoon.
Do Do and Aorn are not the only interesting animals to have a place at Samut Prakan.
In 2001 the farm and zoo became the proud owners of rare twin crocodiles who were literally born joined at the hip.
Regular reptile-themed shows are staged to entertain visitors, one show includes staff going through the risky act of putting their heads inside the crocodiles' mouths.
Samut Prakan claims to have the largest captive crocodile, measuring over six metres long.
