Anne suggested in her comment that possibly the animals I saw on Sunday were groundhogs and suggested I go to Google Images to check it out. This I did.
The shape of the animal pictured there is very similar, if not the same, as the animals I saw. The description said they had black nails or claws and were greyish in color. I couldn’t see if these critters had nails and they were reddish brown in color. If they weren’t groundhogs, then they must be a close cousin to them.
Anyone else have an idea?
