Want to do some good deeds for the numerous winged friends that constantly drop by outside your home? Instead of going through the trouble of building an actual birdhouse, you might want to consider an easier way out without losing too many karma points in the process. We’re talking about the Cardboard Birdhouse, where it is so easy to assemble, you won’t run the risk of hammering your finger by accident. Made out of sturdy cardboard with water resistant coating, it even comes with a wood dowel for the front perch. No idea on how many birds will be able to make a love nest in this though. The Cardboard Birdhouse can be purchased for $4.99.
