I dug this two summers ago; about 9 x 4. Digger loves it and hisses at me when I bring him in at night. I planted bell peppers and squash - not up yet. There is a lot of dandelion, hen & chicks and kale. I bring him in at night and watch his weight feeding him when he comes in. The triple layer cinder blocks are set in the ground and the pit is lined with heavy pond plastic with dirt, mulch and plants on top. He has a log top left that does not show in the picture. He spends a lot of time running the perimeter and goes through the water every time he passes it.
