Designed on the same principle as baby diapers, these litters take a good week without any odor removal and disposal is just as cleanly. Their size is a bit tight for a big cat, thus providing 2 once. Their background, like layers, is waterproof and thus the bottom of the tank clean. In summary, clean, ultra practical and effective (1 week), the litter quickly become essential when one sees the drudgery and the hygiene is somewhat limited as conventional litter.
