Uhhh....I think you got that backwards.
Rabbit starvation is caused by a lack of fat.....not protein.
Yup, same with Moose meat.
No way? Moose will kill you too? Don’t all game animals have a low fat content. Lewis & Clark and company survived on venison and elk until they got to the Pacific NW and injuns hooked them up with salmon, clams and crab...😎
