Now Super Benek Crystal is available in the form of fine grains, which significantly increases its already high efficiency. Granulation: 0.5 mm - 2 mm Super Benek Crystal is a silica gel substrate for animals that absorbs cat urine along with unpleasant odors and any bacteria, and then water evaporates. Advantages: super light attractive price completely biodegradable removes by sanitary means super efficient guarantees maximum hygiene exceptional ease of use (does not require constant refilling) aesthetic appearance Raw material: Super BENEK Crystal gravel is characterized by high purity and moisture absorption efficiency and unpleasant odors. These properties result from the highly developed internal surface of the litter and high porosity (above 80%). The process of moisture absorption is accompanied by a change in the color of the litter. First, the crystals tarnish and then turn yellow. Thanks to this feature, it is possible to control the consumption of litter on an ongoing basis. This litter is a synthetic amorphous silica (SiO2). Application: Pour the contents of the package into the cuvette, maintaining a layer thickness of 6 - 4 cm. Super BENEK Crystal litter does not clump, but completely absorbs liquids dosed to it, enveloping solids with its grains and neutralizing odors. It is recommended to remove solid impurities on an ongoing basis. Liquids absorbed inside the grains of the litter partially evaporate odorlessly. Use the contents of the litter box: until a visible change in color (yellow, dull color indicates complete consumption), until the smells are felt, until the loss of litter in the litter box is 2 cm thick. Expected use time of one package for one cat is 6 weeks.
