I am having the same problem except the only person he is aggressive towards is my DS. I am trying to rehome him cause he really is a good boy, he is even fine with my younger DD. I hate to have to make this guy soup but I will if I have to. I sucked it up and did it with my horrible little cockerals who I wasn't attached to and it really wasn't all that bad after the actual killing part. If I can't rehome this guy I am not going to have a choice, the kid has to come 1st. Sorry you are dealing with this
