13 Eye-Opening Images of Animals in Labs

Written by PETA | April 16, 2015

The pain that animals face every day for product testing, crude curiosity-driven experiments, and deadly medical training exercises are completely horrifying and indefensible. Animals are not disposable laboratory tools, they are individuals just like us who want to be free and don’t want to be forced to endure lives of pain and terror. Take a look at the faces of animal testing and see why we should end experimentation on animals.

Rats and Mice

Rats and mice are not even considered animals under the federal Animal Welfare Act, even though they make up approximately 95 percent of the animals suffering in labs.

Dogs and Cats

Beagle at PLRS

Animals, like this beagle, endured unimaginable suffering at the hands of workers at the North Carolina facility PLRS before a PETA undercover investigation prompted felony cruelty charges to be brought against employees at the facility, which closed its doors shortly after our footage was released.

Robert the Cat

In a crude experiment at the University of Utah, this cat, named Robert, had an electrode implanted into his brain.

Goats and Pigs


The US Department of Defense uses goats, pigs, and other animals for military training exercises, including some that involve live animals being hacked to pieces with tree trimmers.

Monkeys and Primates

Chimpanzees at SEMA

These two young chimpanzees were confined at SEMA, a notoriously cruel Maryland laboratory that PETA helped expose a quarter-century ago. Sadly, chimpanzees still suffer in cruel laboratory experiments at other laboratories.


Britches was torn away from his mother shortly after birth, had his eyes sewn shut by experimenters at the University of California–Riverside, and was left alone in a steel cage with a sonar device strapped to his head.

NIH Investigation: Baby Monkey Alone in Cage

Animal experimenters at the National Institutes of Health continue to perform pointless experiments on baby monkeys wherein the young are separated from their mothers and intentionally frightened.

Monkey at Weizmann Institute

Monkeys and cats are sometimes confined to restraint chairs during invasive neurological tests, like this one, who is shown at the Weizmann Institute in Israel.

Monkey at Covance 1

Monkey at Covance 2

These terrified monkeys are being prepped to have experimental chemicals forced up their noses by employees at Covance, a private laboratory that other companies pay to conduct tests on animals.

These monkeys are a few of the thousands of monkeys imprisoned at the Oregon National Primate Research Center, which was the subject of a PETA undercover investigation.


This rabbit had chemicals dripped into her eyes and rubbed on her bare skin in cruel product tests at a Biosearch laboratory.

Always check for PETA’s bunny logo or search our cruelty-free database to find out which companies do and which don’t test on animals.

YOU can help stop this cruelty. Take action to help end experimentation on animals TODAY!

    Stop experimenting on animals! It’s cruel and inhumane!

  • Sabata Rebekah says:

    Is anyone doing anything about animal testing? The pictures we see here, are these animals in the lab now, or have they been rescued from the snakes that performed these act of cruelty on defenseless animals?

  • Michael Shreve says:

    humanity has time and again displayed not only it’s ability to do cruelity to all types of animals, including humanity, it has also shown it’s likelihood to do it again and again.

  • Dr. Shari Collins says:

    I am soooo upset. How can this happen.

  • dolores says:

    when will people realize that disease is part of life and so is dying. why do humans need to prolong life, especially at the misfortune and cruelty that supports the medical and pharmaceutical institutions? it is truly inhumane and these people should be ashamed for causing them such pain.

  • Mark says:

    I am disgusted with the above pictures how can these evil scumbags sleep at night.

  • Carla says:

    These pictures are awful!!!

  • Felicia Diana Pechtold says:

    Animals are so important! They`re not just beautiful creatures, they are friends and need all our respect and love! They feel, love and care almost similar like humans. But still until now, how many peoble are really interestet in that!?! Unfortunately they can`t speak, but we can give them our voice! It`s never to late! <3

  • leilasmith4450 says:

  • Joao says:

    I would like to help in any way possible, im up for anything from donations to action, its just horrible how animals get treated, and been vegan for 2 years now, but i wanna do something bigger

  • George Limitsios says:

    All these have to stop! Animals have feelings like we do! In analogy.

  • ella says:

    It makes me sick to see this!!! it’s so cruel and so wrong!!! I can’t believe that they can do that!!!! I don’t care what this experiment is for – it is disgusting!!!!!

  • what do you mean by "display name" says:

    Disgraceful. Makes me ashamed to be a human. They should be shot…shot up with a needle of Mercy, Empathy and Intelligence!

  • RemainHiddenn says:

    Y’all are so sick and cruel, if y’all want to test on something to see if a human is allergic to it, how about you request humans to volentire instead of testing on an animal that can’t defend themselves!!!!!!!!!!!!

  • Paula Preedy says:

    It’s disgusting the way these animals are abused. It sickens me to hear its done in the name of science. Animal experiments should be abolished. We are supposed to be a civilised society, yet there is something primitive about these experiments. The animals cannot speak up for themselves. We must be their voice.

  • francine says:

    I am numb with horror and fail to understand once more how humans can consider themselves to be civilised. If I have enough money I will do everything I can to contribute to this suffering by giving more to more animal charities. I hope that my writing and my poetry will allow me some day to change people’s beliefs about our actions on the earth, towards the earth. If there is anything I can do let me know. I would love to write poems or short stories featuring animals and their abuse to you for free, if that is any help. Francine

  • C.P says:

    this is a disgraceful and totally cruel way to treat feelow creatured of this earth … Do you believe animals dont experience pain ? Thi is so very very sad. Anyone who can do this to an animal needs an electrode planted in their brain (if you could find one, much less a heart) 🙁 shame on you.

  • beej says:

    sick sick sick and barbarian…. you would think with technology today people would figure out a different way to do their damn testing and not on living helpless voicless souls… get another human… rub soap in his eyes… does it burn… ok then now we know it burns… easy enough…dont use animals


    Inaceptable, malvado, DESHUMANIZADO!

  • Lizett Alvarado says:

    Please stop testing on live nonhuman animals!!!

  • Michele Robinson says:

    This is so unhumane… Shame on you. I don’t know how you can go to bed a night…

  • Lina Lopes says:


  • Brianna Francis says:

    How can you be so cruel to sentient animals? Even if you do not believe that animals are sentient, they have the ability to feel fear and other emotions, the ability to experience pain and trauma. Don’t be such a monster. Stop experimenting on innocent animals. They don’t deserve this. They deserve love and a good home.

  • Abhishek Tyagi says:

    We were supposed to be humane and they were supposedly animals.
    How do we get to treat them like that and not get punished.
    We better get our act together or we all will suffer even more.

  • katteria says:

    i do not have the words to say how i feel animal testing need to stop

  • Kristen Kneer says:

    ABSOLUTELY DISGUSTING! How can people get away with doing such horrific things to these poor animals!

  • Arja Sharma says:

    Last month, the European Union finally passed a law that has been necessary and called for for a very long time. No longer can cosmetics which hold ingredients tested on animals be sold in the EU. This also goes for cosmetics that have been tested OUTSIDE the EU. It is the first step on a long journey. Our sense of justice cannot stop where our convenience begins. Monsters may not be real, but humans are.

  • Dr. Shane Nelson says:

    God Bless these animals. This kind of experimentation needs to be stopped immediately and the animals released to sanctuaries for the rest of their lives.

  • Kelly says:

    if we know these things are happening, they need to be stopped! It’s cruel and brutalization of animals that FEEL love, compassion, just like humans do! Please stop this

  • Sydney says:

    This is horrible! These poor animals should not be our experiments!

  • gurman minhas says:

    humans are so selfish

  • Eleni Comens says:

    Please send brochures to me snail mail
    To spread info about lab animals also
    info on items that do not test on animals that I can
    get at a grocery store,

  • Ivan Herrera says:

    Stop the cruelty!!!

  • Jen Payton says:

    This is sick and cruel. Only someone lacking complete empathy could do these things to another living creature.

  • Manuela says:


  • Anette Haugen says:

    This makes me cry my eyes out…. Who are we to treat these sentient beings like this? The only evil on earth is human…….. Stop the madness now!!!!!!!!

  • Anja Kilian says:

    Eiscustin, barbaic and useless. Shame on our apecies…..

  • Caren Kipling says:

    Senseless experiments on these poor animals that feel pain, this is just a form of torturing defenceless animals for nonsense experiments

  • Joanna says:

    My heart hurts me, when i watch these pictures. I can’t imagine, how people can do it to them. Where is the God in this moment? Oh, he only punishes people, who hurt other PEOPLE… or monsters?

  • Nancy says:
