This is a groundhog, and animal native to North America. They weigh around 8lbs (3 kg), and can grow a bit over 2 feet tall.
These animals are very shy, and if one gets approached, surprisingly, it won't rip apart a fully grown man, unlike a wombat! Groundhogs are peaceful creatures!
That being said, just because one native animal isn't a "killer animal" doesn't mean the entire continent doesn't have any. North America has the mountain lion, the brown recluse, brown bear, etc. Australia still has killer animals that will **** you up, just because they have native wombats doesn't mean they don't.
