I thought there would be too few fleshy parts. I may have to reconsider.
The grey one has much more flesh than the European brown one. Couple of years ago, in England, there were recipes for squirrel dishes, with the goal to bring the population of the American squirrel down. There also were feeding devices that only could be used by squirrels light enough not to fall through, to give the European squirrel a head start.
Where I grew up, there were quite a few. Loved seeing them race through the trees. Still look for them, when visiting my mother.
