My kitten and ferret wont get along please help!?

i have 3 ferrets and just recently i got a kitten. shes very playful and when she tries to pounce and play with my youngest ferret he takes it to heart and chases and bites her and wont let go until i scruff him and open his mouth manually... its getting to the point where my oldest ferret will see him do it and she'll decide she wants to bite the kitten too... what should i do to keep peace
