A school in Nevada, USA, has been urged to stop a game of basketball where the players ride on donkeys.
The People for the Ethical Treatment of Animals (PETA) has issued an "action alert" on its website asking people to contact the school district and the principal and tell them to cancel the fundraising event, scheduled for March 1.
However the school district superintendent, Caroline McIntosh, says she has no plans to cancel the event, which is apparently a tradition at Yerington High School.
But she says she will make an effort to ensure the donkeys are treated humanely.
PETA says the event encourages children to be cruel to animals, and says the game is also dangerous for the human participants.
Here's a video of an event taking place back in 2007 - see what you think.
It looks like a lot of fun. And the donkeys don't seem to mind too much. Although it's amazing that "health and safety" hasn't put a stop to it. Particularly in a country where people sue at the drop of a hat.
But PETA says on its website that "donkeys who are mistreated or forced into loud, confusing environments can become frightened and may lash out to protect themselves".
Buckeye Donkey Ball, based in Columbus, Ohio, is one company that runs a number of donkey-related games, including Donkey Basketball, Donkey Baseball and Donkey Racing.
This company asks all participants to sign a waiver, which includes instructions about how the donkeys should be treated.
It includes the instruction: "Players MUST NOT pull hair, ears or tails of donkeys or each other. Use caution when catching a donkey and please stay off his rear end at all times."
So what do you think? Does this game look cruel or harmless?
