One of a Kind 6 Foot 2 Inch Cedar Cat Tree - I love the basket on top! Made a cat tree once and it had natural logs in it. cats went apeshit over the real wood. It smelled like outside so the indoor cats loved it practically more than catnip!
burlap kitchen curtains coffee sacks fit the width of the window perfectly. All I did was attach them to the inside of the window trim with screws, bunch up the fabric and tie it with hemp twine that I already had. Simple and cheap!
