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.
