I'm moving my ferrets to new accommodation and I've got a single hob I'm not sure what to do with. Is it bad for an uncastrated hob's health if he is left permanently to run with jills which get jabbed each year? Frustrating obviously but will he suffer physically if he is in mating fettle around unresponsive females? Should they always be separated except when brought together for breeding and if a single hob is separated would he be happier with another hob companion or would they fight?
