150 days that a groundhog hibernates, all without eating!
37 degree body temperature during hibernation - down from about 99 degrees!
14 pounds a groundhog could weigh
8 mph is the top speed of a groundhog, too slow to evade a predator like a fox that can hit 25mph
5 heartbeats per minute during hibernation (down from about 80 beats per minute.)
2 breaths per minute during hibernation (down from around 16.)
1 pound of vegetation is how much a groundhog may eat in a single sitting. (Like a 150-pound man eating a 15-pound steak!!)
1/16 inch is how much a groundhog's teeth grow EACH WEEK

Rohrer - we are not really having a winter yet. I hope we get one and I really don't mind if there's still snow in March. Now if I lived where YOU do, it would be a different story!!

No clue about the breathing. That is really interesting. Hope your winter is shorter and that the little guy sees his shadow:)
