Students in a biology class performed a choreographed dance routine with dead cats

An Oklahoma school expressed concern and disappoint over a video that went viral showing students in a biology class performing a choreographed dance routine with dead cats.

In the video, students dressed in lab coats at Oklahoma City's Harding Charter Preparatory High School hold dead cats, that were to be used for dissection, and manipulate the animals in a set of moves to music used in a cat food jingle.

"Animals should be treated and handled with respect and dignity, a standard that was not upheld in this instance," the school said in a statement.

"These students made a mistake and they will most likely make other mistakes in their lives," it said.
