PETA has obtained a disturbing video that was apparently filmed at Oklahoma City's top-ranked Harding Charter Preparatory High School. The footage depicts heartless students wearing lab coats and playfully dancing with dead cats slated to be dissected in their biology class. The video of the choreographed display was posted on social media, and the students' teacher was even tagged in the post.Students learn faster and better by using non-animal methods such as interactive software programs, and with these modern tools, they don't learn to treat or think of animals as equipment to be used and discarded.
