When I think of rats I mainly think of the gross rodents carrying the Bubonic plague. I never really connected how rats domestication and alterations over time paralleled with urbanization and human development.  Burt talks about how powerful and destructive rats can be and that the major way to control their populations is because they end up self destructing and eating their own. Rats and mice show up in historical/biblical/ancient references but are generally considered sewage rodents and not are not cared for like other “cuter”animals. However, there contributions to science and discovery is something we should be very thankful as a species for.  “The bioengineered mouse,” Donna Haraway recently wrote, “is simulataneously a metaphor, a technology, and a beast living out its many layered life as best it can.” Indeed, in order for this creature to be able to live its life at all, it must inhabit a technosciencetific reality that is perhaps inevitable, perhaps not-but its most certainly a world of our own making. This was an interesting summary of part of the Rader article because of how humans have redefined and controlled the role of rats. We have almost created a new type of rat altogether, except instead of using it for food/dairy we use it for medial advancements in our own species. Where would science be without the lab rat?
