(or doorstop). Method: Cut out two ears and a tail (approx. 2x30 cm) from felt. Fold the tail in half and glue the ends together. Cut the plastic bottle into two pieces. Draw a vertical line on the bottle where you want the cat's face to be. This will facilitate placement of the ears and tail. Brush the inside of the bottle with oil and fill with concrete. Place the ears and tail and let the concrete harden. Draw eyes and a nose and paint rosy cheeks.
