Two sisters in Nandi County have weird cravings.
Sharon Chepchirchir, 24, and Lydia Chepkemboi, 17, have been munching bar soaps since childhood, the same way others enjoy their chocolate.
Their strange behaviour has baffled many at Kiboji village in Mosop, where they grew up.
To establish the cause of their insatiable appetite for soap, the girls have undergone a series of tests at Oak Tree Hospital in Eldoret.
Doctors on Wednesday said they would undergo more tests before they conclude a medical report on their condition.
Four samples of soap had been taken to a lab at the University of Eldoret for a chemical analysis.
