We got some kinda grey/fox hybrid intermingling going at my grandparents place. Size wise they're inbetweem a fox squirrels and greys, Looks like a huge grey or a small fox squirrel. They're all grey with a red saddle on their back some bark like a grey other bark like a fox squirrel. When they go through the woods you'd swear it was a herd of armidillos had one scare of a fat old doe once after it climbed out on a tiny limb and past the weight limit of the branch and fell off hit the ground like a sack of bricks about 10ft from the doe
