Because it's safe to flush, Pet Ecology Perfect Litter™ "Alert" does not contribute to the destruction of our landfills posed by clay based litters. Our 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™ "Alert" is equivalent to 14 pounds of regular cat litter. Our litter uses a unique and safe 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™ "Alert" safe for environment, but it clumps instantly, is flushable, tracks less and is dust free. If that is not enough, Pet Ecology Perfect Litter™ "Alert" is the only litter to offer our exclusive patented early warning system for FLUTD, a potential fatal disease that affects millions of cats each year.
