Greta The Groundhog

Isn't she cute? I don't know for sure that she is a she... I just thought Greta sounded nice with Groundhog.
She lives somewhere in the woods behind our house and has visited us a few time in the past few weeks. She sneaks under the fence (not sure how she fits), munches on the grass for a few minutes, then sneaks back under the fence. I think I'm going to put wire fencing around the back garden when I replant just to be sure that Greta doesn't get a taste for snap peas.
