What temperature do groundhogs like?
Middlesex County New Jersey
The normal body temperature for a groundhog is 97 degrees Fahrenheit. During winter hibernation their temperature will drop to 38 degrees. Their thermoneutral zone is, I am guessing here, probably between 65 and 85 degrees. This would be their comfort zone. I guessed 65 to 85 because I don't have a better reference for you. This range is similar to some other rodent/mammals.
