Thanks for sharing this great post! Very cool that you were able to get some pallets at no cost. It is amazing what people are doing these days with pallets. There is basically a whole subsection of Pintrest dedicated to it. I am always surprised at the things my wife shows me that people made. Would it be possible for you to attach four of the planks you pulled at the corners and wrap some chicken wire around the garden? That should keep the cats and other critters out.
