It's Winter...........Richard and Vicky (our pigs) don't like that cold Sacramento air blow'in in their den. I took the empty grain bags, made of nylon......modified them to act like a wind / cold shield. Very happy soundings of oinks ........coming out from the den. No grunts.
Now you can do this with expensive rubber mats or some other material.......spend $30 - $50.....to get the same results.
I love my money. Oink oink!
