Catsan Smart Pack Cat Litter is an alternative, more effective solution for dealing with Cat waste.The Smart Pack is a unique product that not only contains a layer of anti-bacterial Catsan Hygeine, but has a super absorbant microfleece that improves odour binding and keeps litter trays noticeably dryer for longer.The fleece actively absorbs liquid underneath the Hygiene Litter and locks it in safely. One pack can last you for up to a week, and can then be easily disposed of - or topped up with fresh Hygeine litter.This is the most effective and convenient Catsan solution, and keeps your home smelling fresher for longer than ordinary lightweight cat products.
