The newest innovation from the company that introduced North America to its first silica cat litter is Litter Pearls Micro Crystals. Like all the other fine products from Litter Pearls the new Micro Crystals are made from high quality ingredients that deliver superior results. Litter Pearl Micro Crystals are different because they are soft on the cats' paws while offering superior absorption and odor control. Each small silica gel crystal is able to absorb its weight in urine. The silica gel will then let the moisture evaporate while trapping the odor controlling substances inside the crystals. Keeping the litter box odor free for a month is as simple as daily removal of solid waste from the litter box and a few moments spent stirring and raking the silica to turn the crystals so those on the bottom are brought to the top to aid the evaporation process.
