well its more important if you have a jill to keep her accomodation nice & clean when she is in season as the swelling can get all nasty , either mate her, run her with a vasectomised hob (prooven) or get her speyed if you deffo dont want to breed
Hobs will come into season early next yr if you want 2 ferrets & choose hobs you may have to seperate them when there in full blown season, some people dont have a problem with hobs scrapping , but if you plan getting one of each then just watch for the jill swelling & if you dont want to breed them remove the jill to a single cage ,
