SAN ANTONIO – Did you know cat intestines are so strong you can use them as a jump rope?

A Winston Churchill High School science teacher was allegedly attempting to demonstrate that marvel of anatomy during a recent classroom lesson, and two videos recorded by students and posted online through the SnapChat app are now causing problems, KSAT reports.

People for the Ethical Treatment of Animals were among the first to condemn the science lesson.

“Studies show that classroom animal dissection can foster callousness toward living beings, and these gruesome ‘jump rope’ videos are a particularly sad example,” PETA youth director Marta Holmberg said in a prepared statement. “PETA is calling on Winston Churchill High School to teach its students to respect life and science by replacing crude and cruel animal dissection with humane and effective non-animal teaching methods.”

PETA captured the very brief videos and posted them to its website just in case anyone missed them.

The first video shows the cat intestines stretched between two students, who used the internal organ as a rope while a third student jumped in the middle. A second video shows a student jump-roping by himself and briefly flashes to students working on a dissection.

North East Independent School District officials told KENS the teacher was simply trying to demonstrate the length and toughness of cat intestines, a lesson she learned in college.

“This lesson really was not meant to be disrespectful or degrading in any way,” district spokeswoman Aubrey Chancellor said. “And when the teacher (and students) found out that that’s how it was being portrayed, they were actually very upset about it.”

“The lesson was intended to demonstrate and explore the strength of the organ,” she told KSAT. “The teacher participated in this same lesson in her college courses at Texas A&M.”

One student told the news site he’s offended by PETA’s depiction of the lesson as animal cruelty.

“Being a student in said class, I am overwhelmingly disappointed in the negativity that is directed, not only at the anatomy program, but to our school as a whole,” the unidentified student said.

“I value every animal life and would never engage in any activity that I believed would be disrespectful to the animals I am examining, and I understand that to someone from the outside looking in may take offense to the acts of several individuals … in the video, however the activity took place in order to more thoroughly understand the length and strength of the intestines that we were studying.”

District officials told the media they’re now looking for an alternative lesson that’s “equally as effective” as using the cat organs as a jump rope. She said neither students nor the teacher will face discipline over the videos.

“If we can find a lesson that is equally effective as this one and doesn’t offend people in the process, we’re going to call it a win-win,” she said.
