Ya, well -- if I ever need to do beet pulp again, it will be fully and well soaked. I can only get big pellets here -- about 1/2" in diameter and 1" long. They expand to four times their size when wet. I can't see that not causing problems in their digestive tract or even on the way down if, heaven forbid, one got stuck. And I can't see it fermenting in my neck of the woods that quickly. This is not a humid or hot area. Winter is cold, cold, cold and it only get truly hot here for about 4 weeks in the summer. And it's a dry heat.
