How long did Kaguya live?
Most lab mice live two years, if they are not killed in an experiment. Kaguya would be almost three and a half now (she was born in early 2004) so Kaguya, the first animal with two parents of the same sex, has probably died by now. There were no follow up stories on her lifespan, we only know that she survived to adulthood and had a litter, which usually happens at about 50 days. Did she make it two years? How are her children doing? Did anyone ever repeat the experiment, in mice or other animals?
