The pro’s and cons

Animal testing is also known as the use of animals for scientific experiments. Most animal testing is done by universities, pharmaceutical companies, and medical schools. Most animals used for research are breed for the specific purpose of testing and few animals used for testing are captured from the wild.

They use animals for basic research such as behavior studies and genetics while other animal testing is done for the benefit of humans. This research includes drug testing, surgical procedures, medical equipment, and somewhat inconsequential applications like; cosmetics, and other household products.

Here are some pro’s and cons that are mostly mentioned about animal testing:


o Finding drugs and treatments to improve health and medicine. There are already some lifesaving medical breakthroughs that are the result of animal testing, like open heart surgery, organ transplants, effective insulin, vaccines for deadly diseases, …

o It is the most accurate way to learn the effects of substances in a living body

o Ensuring the safety of drugs and other substances

o Human harm is reduced and human lives are saved but also animal lives are saved because of animal testing.

o Many of the medications and procedures that we currently use today wouldn’t exist and the development of future treatments would be extremely limited.

o Many argue that the lives of animals may be worthy of some respect, but the value we give on their lives does not count as much as the value we give to human life.

o Using cell cultures can only reveal side effects on a molecular level and cannot unfortunately, reveal side effects like organ failure, rashes, tumors, or cardiac arrest like animal testing can.

o Using computer models cannot always predict unknown variables that can be discovered with animal testing.

o Animals may not have the exact same philology as humans but animal testing is accurate enough to test whether a substance is even safe enough for human trials.


– The costs-
The housing of the animals, feeding, carrying, treatments, controlling the environment, is very expensive
Animals used for testing are usually obtained from specific breeding facilities and come with a high price tag.

– Morality –
Animals have the right to live their own life; and we are not allowed to meddle with them just because we can.
It is not worth euthanizing animals for the benefit of mankind.
The animals are mostly euthanized after research or others are wounded and live their life in captivity

– Necessity/validity –
The drugs tested on the animals will never actually seem to have approval and have benefit to humans.
Sometimes it is not important enough to sacrifice an animal, like testing the effect of cosmetics and household products.

– Usefulness –
Animals kept in unnatural conditions ( a lab and not their natural habitat), or animals in pain or distress, are not giving rise to accurate or consistent results. The reaction of the drug in the animal’s body versus the human body is different. Humans are quite different from other animals, so the consequences of animal testing may not be applicable to humans.

    Animals also have the right to live, as Gerty already said. Therefore, to reduce, refine and replace animal testing, investigators should search for alternative test models if possible. In vitro techniques are considered as important alternatives but lack the complexity of the human body. The use of lower organisms can complement these shortcomings [1]. As lower organisms, they could use bacteria, fungi, insects etc. For instance, to investigate whether mutations occurred or not they can use bacteria. Besides, modified microorganisms can produces substances which animals also can create [2].
    Other alternatives due to advances in technology are magnetic resonance imaging (MRI) and telemetry. These are methods to follow the physiological processes in animals, without treating the animal [2].

    All these methods are applied currently. So I think scientists are doing well to decrease the use of animals and increase alternative test models to investigate diseases etc.

      What if you were those poor suffering animals. You couldn’t fight back, sitting in your Cramed cage waiting to be eiather tortued or killed!!!!

    Other alternatives to animal testing:

    Many scientists feel that animal testing cannot be replaced completely by non-animal methods, particularly in biomedical research. They say we simply do not yet understand the complexities of the body well enough to be able to design suitable non-animal alternatives.

    The use of alternative techniques leads not only to more reliable scientific conclusions, but also to a more humane approach that, in many cases, can replace live animal use completely. The three categories of alternative techniques in research and testing are commonly known as the “Three R’s”:

    – Reduction: minimize number of animals used
    – Refinement: minimize suffering and distress
    – Replacement: avoid the use of living animals

    For example:
    – Not so many years ago if a woman wanted to find out if she was pregnant, a laboratory test was used involved killing a rabbit. But now she can just buy a small kit in a store that tests your urine! The rabbit is replaced.
    – Another sort of a replacement test is the “synthetic skin”, called Corrositex. It is used to see whether a substance will burn or corrode the skin.
    – Computer modeling: High school biology classes, for example, might practice dissection on a computer model rather than on real, live frogs.
    Here is an example:
    – Improved statistical design: investigators can get the most out of the data generated by each animal they use and so need fewer animals altogether.
    – Sharing research animals is also a reduction method
    – Techniques that are less invasive to the animal also may constitute refinement. For example, researchers can use such modern medical technologies as ultrasound or Magnetic Resonance Imaging (MRI) to look at what is happening inside an animal without cutting into it.

      More alternatives summarized:

      – Epidemiological study’s
      – Clinical research
      – Genetic research
      – In vitro study’s
      – Stem cell research
      – In Silica Research
      With respect to all calculations and simulation techniques using computer technology.
      – Advanced art models
      Art Models may in some cases be used as representation of the human body.
      For example the anatomical models used in the education, crash test dummies instead of monkeys., robots,…
      – Imaging study’s
      For example the CAT-scan, MRI, PET scan, ..
      – Lap-on-a-chip
      – Micro Dosing
      The use of volunteers under controlled condition that are exposed to a very low dose of a substance.
      – Review market research
      – Autopsy’s and post-mortem studies
      – Prevention
      Pollution, unhealthy diet and lifestyle

  3. i say no because its wrong ,cruel , and just not right look at what we have from them …
    the people that does this how does it make you feel… if it feels wrong then why do Inessa on doing it? if you were the animal how would you feel and you couldn’t do nothing bout it .Would you feel sad , scared ,in pain, afraid, felt like no one can help you, felt like you just wanna die and put this out of my misery, crying or trying to scream for help and no one could hear you but only could hear the noise of nothing
    You think that’s its right for people that don’t even deserve it … if you would just listen to them you can see that each night they’re there they praying or wishing for them to just leave for them to just not to come thru that door . they cry each night you may not think they think that or feel that way but what would you know ….. how can you live wit yourself just think bout all that

    I think animal testing for medications is fine, but for cosmetics… COME ON!! We are wasting animals life so we can make outselfs look pretty. Animal testing should now and forever be taken down to a minimum!

  5. Evan says:

    If you guys are so worried about losing a life of an animal then how about you take its place, be the test subject and yes I know that using animals for test subjects is cruel but life will be hard, there will be alot of people that would die without animal testing. l say using a couple of animals for testing drugs or chemical would save a couple of millions of lifes or more.

    Would you use a life to save a life or be the cause of millions of deaths?

  6. Breanna b says:

    F u!!!!!! U want to test on animals when you don’t know is it’s valid or useful? You think the only con is cost, then test it on your self! Then feel free to rewrite the con section!

    • Breanna b says:

      You think you have the right to kill animals for no reason at all!!!!! Learn right from wrong, did you go to kindergarten. Your better than that. Watch yourself. Cause when I am incharge his will all change!!!!!!! So you better watch out!!!! Test on yourselfs!!!! You freaks!!!!!

  7. Kyla Murlin says:

    I’m both for this and against it. I’m for it because we have made several medical breakthroughs thanks to animals, such as finding out that insulin helps people with diabetes, some cancer treatments, vaccination for rabies, etc. I believe that as long as the animals are treated with respect and care then it is alright. Yes, I know it doesn’t always happen, but I think God gave us animals so we could learn from them and use them to our advantage.
