I have a workable ferret barrier that also doesn't look too terrible. How to explain it? Home Depot sells a PVC lattice, the type of thing you put under a deck or porch to block the view under the house. The PVC slides into a special molding, also white plastic, that is about 1 inch by 2 inches and has a deep groove in it. An 8 foot piece of this molding costs about $4. I cut two 2-ft pieces of this molding and screw it into each side of the door frame I wish to block. It doesn't have to be flush to the floor if there is a saddle. The two pieces then form a slot in which to slide in a removable panel. Although the molding looks like you can't screw it into the wood, I used long sheetrock screws and an electric drill. The head of the screw pushed the groove apart and then countersunk itself into the doorframe. The panel is thin white melamine, the type of cheap paneling used in bathrooms. Cut the panel to fit the space, in my case, just under 30". I cut it 25" high, which so far is high enough to deter leaping weasels but low enough for poor old mom (me) to clamber over. It's also very slippery. The paneling and the molding cuts easily with a saber saw. The whole thing looks clean and white and not too bad when company's coming! It's also easy to lift in and out whenever you want. Happy barricading! Kat [Posted in FML issue 2316]
