Ruggers you are right some ferrets do pull em out, but they don't mean it, see a rabbit tunnel usually goes only 2 directions, sometimes a ferret will drag a bunny out, but same ferret is just as likely to drag the bunny deeper, just depends what way it's pulling I suppose, I'm not saying you can't train a ferret to cache, I don't know either way. But I'm looking at my ferrets a bit different now as to what I could do with them to keep an ticking over in summer especially
