As long as there are no additives, ie pesticides, it is the same thing. The pet market is a huge buisness now, so if they can lable something for pets they can jack the prices way up. IE a 50lb bag of feline pine pellets is $30, a 50lbs bag of wood stove pellets $5. 1lb bag of hay marketed for small pets $5, a 60lb bale of horse hay $3.
