Animals also enjoy cinder blocks
If you love animals or have a lot of pets, this hack is perfect for you. Cinder blocks can be beneficial for humans, but they can also work to build beautiful houses for birds. Having animals close by is always nice.
Keep the birds protected with this cute little house. Just take a cinder block and put a wooden cylinder through it so the birds can perch there. Then, hang the block from a tall tree. Make as many houses as you want and paint them in any color.
