Yes, its prepared just like ground hamburger in a big pot with a little salt. Cooked sawdust(4lbs) is placed in a tupperware and stored in the ref. It'll keep for a couple of weeks. My lab and kitties love the stuff and healthier for them than commercial pet food.Vet says its fine, high in protein and calcium. I don't feed them raw sawdust ,it might be contaminated w pathogenic microrganisms.Cooked sawdust??
