It looks kinda like a muskrat to me- http://en.wikipedia.org/wiki/Muskrat Those claws on it's hands and feet look pretty wicked.
Very cute - beware of the momma groundhog - they can be really fierce when guarding their babies!
Could it be a baby porcupine?
He is cute, Lizzie is into ground hogs, gophers, anything that pops its little head out, so good thing she did not see it she would have never left, LOL. That is a great picture of the little guy!--Kathy
I love groundhogs!! What a cute picture.
Rebecca, I think you're right actually, we've looked at more photos and we think it's a muskrat!
