To Donna in Germany: 1 - Fact - whole males stink ONLY when in season - when not in season they don't stink any more or less than a neutered male. If you have your male vasectomized rather than neutered, the only difference between that ferret and a whole male is that one is fertile and the other isn't. The vasectomized hob will still stink when in season, will still be looking to mate when in season, and essentially will have the aggressive nature of a whole male looking to breed with a jill. Unless you are a breeder, why would you want to vasectomize rather than neuter? I don't really see any advantage, in fact, IMO, I see it as a disadvantage because you will still have to put up with a stinky ferret in season, he'll still be marking with smelly urine, and you probably will have to keep him separated from other ferrets when he is in season. If you have allergies to a whole ferret, then the best action to take would be to neuter (no need to descent). Debbie Riccio WNYFLFA Rochester, NY [Posted in FML issue 1557]
