Take the hangers apart with pliers and shape them as shown on the picture, using a tape on the top (wide enough to put the pillow and the cardboard inside)
Strech your t-shirt on the construction leaving sleeves loose for additional entrances or tie them at the back of a tent. Here it is. The easiest house for cats ever!
