Where in the world is it possible to eat wild grass seeds all year
around?
Grains can not be a natural predominant food for any species.
I think they eat various seeds and veggies, and also a lot of insects.
Laboratory mice are served grains, so that they can be compared to
humans
who is generally considered to be a grain eating species. The mice
