So I carry a single strap pack, a snapsack when hunting . Both ends cinch closed. At the bottom I have my drag rope for deer. So...
I open the sack and pull out the end of the drag rope about 6", Leaving the rest tied up in a bundle, and then cinch up the bottom of the snapsack around this protruding piece of rope.
THEN when I get a bushytail, I untwist part of the rope, which has a whipped end. I untwist it enough so that the squirrel's head fits through the rope with one strand around the neck, and then I allow the rope to retwist..., a voila, the squirrel is secure. The next squirrel gets the same setup, BUT I use a different piece of the rope to form the gap for the squirrel's head. Their mutual weight makes the rope want to twist and clamps the strands down well on their necks. So they hang as they would from straps on some styles of game bag, but I don't need a game bag.
If I get really lucky and get more than a pair or so..., I pull out more rope, and tie the loose end around where the strap attaches on the pack at the other end. The rope is then parallel to the snapsack, coming out the bottom opening and attaching at the other end. Thus it's away from me, so dangling squirrels don't drip blood on anything but the forest floor, AND as they are behind me with the pack on my back...don't snag on brush.
