A hyena may not be your average house pet, but in northern Nigeria some men keep the creatures in their homes, display them at festivals and even use their dung or saliva to make remedies.
Kawu sells remedies made from hyena dung, saliva or hair, which he says can help with a range of ailments -- even bad behaviour by teenagers.
"Some young people, they get into drugs, alcohol. The parents come to me and I give them a remedy so that everything will be all right," he said.
