I agree. Mine haven't changed their behavior towards me because of their food. They are more food/prey driven, but not aggressive. The whole group are cuddle bugs.
Compared to cats, ferrets mean business when it comes to live prey. In my personal experience, I haven't seen a ferret play with/torture their food. Feed a reasonable size prey and its a one hit kill. They latch on behind the neck and break it. Mine start crunching on the face after the prey is dead. A whole prey fed ferret's food drive is insane compared to the kibble eaters. But I suppose if you fed an adult jumbo rat, it would be agonizing if an inexperienced ferret has no idea how to dispatch it.
