Let the Battle Begin! No matter what my Nana does, something is attacking her garden and eating all of her vegetable plants, over and over again. Nana tries everything she can think of to keep the critters out, but nothing seems to work. What kind of animal can be so hungry that it bites through fences to get her plants? And what will Nana ever do if she actually manages to catch it?
