Stove pellets, or wood pellet bio-fuel, can be made from all types of wood, wood byproductsand recycled material. Most brands are made of at least 80% hard wood to provide maximum heat and longevity when burned.
Pelleted wood bedding is made only from soft woods. The quality pellets are made from virgin soft wood. Theyprovide the greatest expansion, absorption and odor control, with least possible dust and no risk of any contaminants.
Well I use the wood stove pellets in my horses stalls. The ones I get are all natural. So I use them as litter for Rue as well.
The ones I get are a hard wood. A huge bag is $6 and its going to last me forever. We buy 20 some odd bags at a time for the barn. I feel safe using them for my show horses there is no reason I can't use them for Rue's tiny litter box that he stands in a total of 5 minutes a day. However I also change his litter twice a day because I am anal like that.
