The tofu cat litter is made of food-grade soy pulp that would otherwise end up in the landfill and is safe and reliable for your cat to use. Absolutely no artificial additives added. This upgraded version is specially added with all-natural active charcoal to deodorize more effectively while the scent remains natural fresh so that you and your cat can breathe comfortably. The tofu cat litter has amazing liquid absorbing power. It can absorb a liquid volume four times greater than itself in just two seconds. The faster and the more amount of liquid the cat litter can absorb, the quicker the odor can be suppressed. Every granule is made to have a diameter of 2 mm and as a result, the tofu cat litter is soft on paws, great on suppressing odors and save on usage. The all-natural soy pulp has good water solubility so you can just flush it down the toilet. This scientific formula improves the efficiency of the cat litter so you can save on usage and save trouble.
