Mishaps with Mice – Lanna A

“Nobody keeps a tally of the numbers used, but often-quoted estimates put the figure in the United States alone at well over 10 million animals a year, the vast majority being mice.” (pg. 74). So I’ve given you a number, but why is it significant. What if I told you that this was the number of animals used in scientific experiments every single year. Shocking, right? Well here’s a little bit more news. “Certain drug-toxicity tests run separately on rats and mice only reach the same conclusion about 60 percent of the time. And if mice do a so-so job of predicting what will work in a rat, then we should be very humble about what they tell us about human beings.” said by Thomas Hartung at John Hopkins University (pg. 72-73)

Many scientists have had their fair share of breakthroughs, specifically in medicine and/or healthcare. Unfortunately, this is through the experimentation on hundreds of poor lab rats. They are kept in sterile and homeostatic conditions, though none nearly as luxurious our friend Remy’s life here.

In fact, most labs tend to live in stacks of smalls cages lining the walls. The rats or mice are placed in the cramped living quarters, and are forced to live out their days hardly moving unless being poked with a needle. In some extreme cases, the scientists will end up starving the subjects because they are simply not feeding them enough.

Science Magazine (link above) performed a test proving that rats with more room to run around, stand up, or even burrow, had very different results than rats who were held in very confined cages. They stated, “Mature rats can reach almost twice that height when standing…In the new experiment, scientists observed rats in much larger, multilevel habitats with a height of 125 centimeters. Compared with their tightly caged counterparts, who were unable to stand upright.” Not only were the ‘free-range’ rats more active, they produced healthier results as well.

Something else that Richard Harris mentioned in his book was the accuracy to real life. What usually ends up happening is that a scientist uses, say 100 female rats, born in 2008 around September maybe October. Then, they are cleaned with harsh chemicals everyday to avoid any outside germs that might affect the results. However, with your average human being, you won’t find that. These drugs must be sold to people of all ages, and all genders. There is also a guarantee that at least 98 percent of these people don’t bathe in bleach everyday or stay inside.

Joseph Garner at Stanford University

Animal behaviorist Joseph Garner conducted an experiment with half of his mice in very similar conditions to ones listed above. The other half were kept in a normal ‘free-range’ setting with mice of all kinds. Surprisingly, the latter part of the experiment produced more consistent results than the so called “control” of the test.”Garner said cage position is enough of a difference to affect the outcome of the experiment…Scientists have only come to realize that the sex of the person who handles the mice can also make a difference.” (pg. 80)

With shocking results such as these, I ask you, are the 10 million animals’ sacrifices really worth it?

  1. First off, I really enjoyed how you hooked the readers in by adding a question after your found quotes in your first paragraph. I found your blog very organized and well written with a lot of useful information. I completely agree with the statements you made about how the mice/rats are living in very bad environments for the use small science experiment outcomes.Throughout your blog, I can tell you were very passionate about this topic which showed through your writing which I also liked. I also agree that it’s not worth all the lives of the animals used for science experiments. I overall enjoyed reading your blog post, nice job :).

  2. I really liked how well you described the living quarters of the mice and how they are not very sterile and how they are cramped which can really affect the results of lab tests an waste a lot of money. Very nice job organizing the post and your pictures were very relative to your post. Good Job!

  3. I’m not sure there’s much to say about this. You did an amazing job explaining everything from only a 20 something page chapter into one paragraph. I like how i’m able to read this and know you were very passionate about this subject and completely agree about the living circumstances these animals have to go through for most of the time not pretty endings. You have me all the way that these animals are not able to be animals on their own for others peoples pleasure or jobs. I hope mine come out this well. Loved it! -Cyanna M

  4.

  5. Lanna, while I was reading this chapter, I had a lot of similar thoughts to those you shared in your blog post. I was extremely surprised to hear about all of the variables that went in to experimenting with mice and like you, I wondered is it really worth it to test on so many animals if the majority of he results aren’t even applicable to human research? Throughout your blog post, you did a really good job incorporating a mix of your own opinions on animal research as well as quotes and statistics from the book which made your claim that too many innocent animals lives are being wasted, much stronger. My favorite part of your blog post was the unique and effective way you layed it out by including quotes from the book and then a strong personal reflection or a question following the quote. This is a really strong blog post and it’s extremely informative about the barbaric conditions of lab testing on animals, nice job!

  6. You did a good job explaining the chapter. I could tell throughout reading this, you were passionate about your topic. I agree with the statements you made about the horrible living conditions of the mice/rats. I also agree that science isn’t worth the majority of our animals lives. Overall you did a great job. -Kerianah M
