Hi Jen and Crew! Let me start by saying that I have come to believe that nothing is truly ferret proof, but only ferret resistant! :o) One thing that has worked really well for us has been some particular cabinet latches. I will do my best to describe them, and chances are you've seen them somewhere before. The latch consists of two metal pieces that fit together. Piece #1 has 2 rollers or metal stubs with a space between them, and is mounted to the inside frame of the cabinet. Piece #2 has one roller or metal stub that lines up to fit into the space on piece #1, and is mounted on the inside of the cabinet door. There is quite a bit of friction resistance when the two pieces come together as the cabinet door shuts. Our furrzies have not been able to strong paw there way in with this set up. However, part of the trick is to get latches that fit together strong and snug, and also to mount the latches at the bottom of the cabinets where the fuzzies are most likely to persist in their ploy of cabinet conquering. Sometimes, my hubby and I have to give the cabinet a pretty good tug at the bottom ourselves to open it, but it's worth it not having to worry about the fuzzy nuts getting in there. If you have particularly persistent ferts, I suppose you could mount latches at the top, bottom, middle, etc.! If that doesn't work, then Bhor help you! :o) Anita [Posted in FML issue 2308]
