Our barn cats have adopted a kindling box we put on the porch, they both love it. It is in the sun for much of the day. Flo usually takes the top of the box, it has a kitchen. Maria is making a pillow or some kind of lining for Minnie, who likes the lower box. They often sleep there at night now. I am always amazed at how cats can make special spaces for themselves, Minnie has also adopted the Fiber Chair, which catches the afternoon sun.
