Guardian Angel pine cobble cat litter is super absorbent, ultra clean and naturally controls odor. 100 Percent pine cobble is a precision screened fiber that, like our pellets, is high heat treated in a process that heats the wood fiber to levels of pasteurization. This is the safest, cleanest, incredibly absorbent litter. Oils in the wood are removed to reduce allergens and concerns of molds, toxins and other contaminants found in unprocessed fibers, woods, corn, wheat and clay are eliminated. Perfect for high moisture environments or for pets that prefer to dig to cover their waste. Comes in 12-pounds bucket.
