Here's why:
* Different species: Head lice are specific to humans. They are known as Pediculus humanus capitis. Ferrets, on the other hand, have their own species of lice.
* Host specificity: Lice are highly adapted to their specific host species. They need the right environment, blood type, and other factors to survive and reproduce.
So, while ferrets can get lice, these are not the same as the ones that infest humans. You can't catch them from your furry friend!
