Why are rats the most common lab animal to do studies on?
Something I know about! Actually, mice are more common, but rodents in general are used for a few reasons. They're cheap, small, easy to handle, easy to house and feed (mmm autoclaved pelet food), can be placed with members of their own species, can't really hurt you, and reproduce quickly.
The Short Answer
Something I know about! Actually, mice are more common, but rodents in general are used for a few reasons. They're cheap, small, easy to handle, easy to house and feed (mmm autoclaved pelet food), can be placed with members of their own species, can't really hurt you, and reproduce quickly. Now, non human primates (NHPs) are a closer biological analog to humans but basically have drawbacks where rodents have benefits (expensive, large, hard to house and feed, low reproductive capacity, can be violent). They're usually saved for later studies after there has been good data generated in mice / rats, if NHPs are used at all. That or studies where a human disease cannot be modeled in another animal besides a primate.
