I probably overlooked that. I always associate the term "experimental" in surgeries with cancer, life-threatening injuries or congenital issues.
Though, there is a small issue *coughs and hums* that must be noticed even if we ignore the primary and secondary sexual characteristics. Unless male and female foxes just happen to have the same pitch of voices.
With all this said, that doesn't makes my dissapointment smaller. What is done, is done, since it was the writer's prerrogative after all.
