Cell-Sorb Plus is a patented paper bedding/litter that keeps cages odor free with very little effort. It is 400% more absorbent than wood shavings. It neutralizes the urine odor (totally eliminates ammonia odor up to 3 weeks) and allows the liquid to evaporate. It even dries the feces. It does not become saturated and cling to cages and litter pans. Flushable. Will not clog pipes, sewers or traps when flushed properly.
