A private school in Miami brought a caged wild tiger to a senior prom - sparking outrage on social media from people who say it was animal abuse.
Christopher Columbus High School, an all-boys Roman Catholic institution costing US$10,700-a-year, held the annual senior dance at the Double Tree Hilton Miami Airport Convention Center on Friday, the Daily Mail reports.
The prom this year had the theme of "Welcome to the jungle".
Organisers apparently decided to take up the theme literally by arranging for a fully grown tiger to be trotted out on to the dance floor.
The spectacle outraged the sister of one of the students, who took to Facebook to express anger.
Castellanos said her brother was unwilling to publicly come forward because of fears of reprisals from the school, ABC News reported.
She said that video of the tiger shows that the animal was being abused.
"The body language of the tiger showed he is not happy with the situation," she said.
"He is stressed. The tiger is pacing up and down."
The tiger wasn't the only exotic animal brought to the prom.
Organisers of the event also arranged for birds, a lemur, two macaws, and an African fennec fox.
The school defended itself against criticism, saying that the animals were minded by state-licensed handlers.
An animal behaviour expert appears to agree with Castellanos.
"The tiger is clearly looking for a way to get out of that situation, it's not difficult to interpret that behaviour," said Ron Magill, a spokesperson for ZooMiami.
"He was surrounded by people, cell phones, lights, jugglers juggling fire.
"The tiger, which was displayed for a few minutes in a cage was never harmed or in danger, was not forced to perform, was always accompanied by his handlers, and for the great majority of the time was lying down in a relaxed state facing away from the audience."
