Pet Ecology Perfect Litter™ outperforms all other litters in every way. The Patented formula is ultra lightweight - up to 70% lighter than regular litter, yet it absorbs four times more than most other cat litters making it last longer. One 2-pound bag of Pet Ecology Perfect Litter™ is equivalent to 14 pounds of regular cat litter. Our litter uses a unique and odor control withy microbial effectiveness that destroys virtually 100% of bacteria, germs and fungus that causes odors before they start up to 48 hours, leaving your home odor free. Not only is Pet Ecology Perfect Litter™ safe for the environment, but it clumps instantly, is flushable, tracks less and is dust free. If that is not enough, Pet Ecology Perfect Litter™ is the only litter to offer the exclusive patented early warning system for FLUTD, a potential fatal disease that affects millions of cats each year. Pet Ecology Perfect Litter™ makes it easier to love your cat even more. Pet Ecology Perfect Litter™ is 100% earth friendly and natural (no sodium bentonite) and biodegradable. Because it's safe to flush, Pet Ecology Perfect Litter™ does not contribute to the destruction of our landfills posed by clay based litters. According to the Bureau of Waste Management, and other reliable sources, billions of pounds of spent cat litter is dumped into U.S. landfills every year - more than the amount of disposable diapers. Moreover, clay-based products swell to 15 times their original size via water absorption, thereby exacerbating landfill capacities and resources even further. Simply put, the clay-based cat litter products that dominate the market today can be hazardous to the environment
