How cute are these guys???? Came across a den filled with young Groundhogs, who were very curious as to what I was doing sitting on the ground watching them. They did not seem to mind my presence, as they would play, and eat within yards of me. Mom stayed back in the brush, but kept a close on on her young. I would say these young ones were about 40% of their full grown size, so probably only about 3 weeks old.
