Up to four times more absorbent than traditional clay litters, therefore reducing the amount of cat litter required and absorbs ammonia very efficiently, reducing its harmful effects on the respiratory system and reduces odour. Cat Litter is needed in the bottom of the litter tray, allowing easy removal of the soiled product, which, added to the increased absorbency, means that it is an economic replacement of clay litters. Can be used for up to 12 weeks provided damp litter is removed. Absorption takes place in depth, retaining urine and odours at the bottom of the tray. Allowing easy removal of soiled product. The weight of the pellets enables them to remain in place when the cat scrapes its litter. The litter stays dry and odourless, and the cat returns there without hesitating. It comes out from it with its paws clean and dry. Made from annually renewable crops and is completely biodegradable, No trees were lost nor land degradation in making Felisorb.
