First off - no! Yes, wood pellet cat litter is cheaper than premium pizza oven pellets. But please don’t consider burning this to cook pizza! The wood in cat litter pellets is of variable quality and may contain chemicals that taint your food. You have no guarantee of the type of wood used, and these types of wood pellets are highly likely to leave a sooty residue on the inside of your pizza oven. Besides - we promise your dinner guests will run away screaming once they learn how you've cooked their dinner. Not recommend. Please don't!
