It's a species close to human, with several advantages over mice: They're free, you don't shave them, they feed themselves, and nobody pickets your office saying, "Save the lab medical student."
To je vrsta bliska ljudskoj, s nekoliko prednosti  u odnosu na miševe: besplatni su, nije ih potrebno  brijati, sami se hrane, i nitko ne upada u  vaš ured uz riječi: "Zaštitimo laboratorijskog studenta medicine!"
