Ananova:

Thai zookeepers are putting their male panda on a diet in an attempt to get him to have sex.

Officials at Chiang Mai Zoo have put Chuang Chuang on a strict diet as part of a long-running campaign to get him to mate with female panda Lin Hui.

Zoo spokesman Kanika Limtrakul said: "Chuang Chuang is gaining weight too fast, and we found Lin Hui is no longer comfortable with having sex with him."

Chuang Chuang weighs 331 pounds while Lin Hui is only 253 pounds, reports Metro.

Bamboo shoots are being cut out of Chuang Chuang's diet and he is having only bamboo leaves.

The zoo have been trying for months to get the couple to mate.

They staged a mock wedding, separated the two to try to increase the sexual tension, and most memorably tried showing them panda porn.
