I'm glad your'e going to do more research, very sensible. I would imagine that keeping them in seperate rooms is probably a good amount of precaution. The only thing that concerns me is the word 'introduced'. I'm not entirely sure what you mean but all I would say is I would never let our ferrets get anywhere near our other pets, even in their cage. They are quick, clever and have very sharp teeth, I don't think it's worth the risk. Tho if you mean acquire both ferrets and chins at the same time and when both are young so they grow up completely separately but used to the occasional whiff of one another perhaps on your clothes, then yeah, that sounds about the best option.
