There should also be some silver half angoras thrown they are no different the normal ferret, and will work just as well.
They will be tame and not hand shy but no different to normal ferrets - I have to disagree. Sorry. They will be far more alert and alot faster. I also find that even the half cross's take a bit more handling to bring them to the same level of tameness. They are great animals though and in no way am I putting them down.
