St. Louis (KSDK) - There was quite a sight outside St. Louis Children's Hospital Wednesday morning.
PETA staged a demonstration to protest the hospital's Pediatric Advanced Life Support, or PALS, which is an intubation program.
Live cats are used to teach health care providers how to insert tubes into the throat of a person who isn't breathing.
It's a very delicate procedure particularly on babies and newborns.
PETA says the practice is inhumane and harms cats.
However, a PALS spokesperson says in program's 20 year history, a cat has never suffered a serious injury.
The cats live in a cage free environment and are eventually put up for adoption.
