no matter how big they are i bet there roach shaped ribcage is easily spanable,wonder how many people have spanned one? it will show you how easy they can get into tight places and how can turn round in such a small place,a dog cant lay with its nose up its own arse like a fox can,and it always used to baffle me how hounds could run a fok to ground in a rabbit set yet it was always faceing the dog when one was put down,,,,you just have to admire them thats for sure
