CAT'S BEST is a pure nature product that is produced 100% from renewable plant fiber-raw material without artificial and chemical additives. CAT'S BEST is manufactured from the finest organic fiber coming from untreated, domestic fir and spruce wood which accumulates naturally in the environmental cycle. By using this wood, we help maintain natural and healthy forests. At the same time, our plant fiber products are subject to the environmentally compatible natural biological cycle from the plant seedling to the rotting biological decomposition product. Anti-microbial effect of the cat litter. The result: less odour, better hygiene.
