Hi to all. Here is an idea that my husband and I came up with to keep fuzzies out of rooms they are not suppose to be in. We have a spare bedroom that our fuzzbutts thought belonged to them. They were going under the door to get in. Needless to say they were making a mess in there. So here is what we did: Measure the door and go to you local hardware store and purchase door sweeps, they are made for your exterior doors to weatherproof. Make sure you get the 2" kind or wider to really make the door tight. Then just screw them in place at the bottom of the door and you should have a ferret proof door. It worked for us. Let us know if you have tried this or have questions. Wendy & Doug and their two fuzzbutts; Sable and Bear=20 [Posted in FML issue 2879]
