Banish litter tray odours forever! This revolutionary new product traps urine and destroys the smells that arise from used cat litter. One application will double the life of your cat litter. Cat Litter Deodoriser is completely biodegradable, pH neutral, and totally safe. The unique Urine Encapsulation Technology quickly renders the litter odour free, and the blend of friendly bacteria, which subsequently eat the urine, keep it that way. Urine encapsulation works so fast that only a little perfume is needed in the product, which is a major benefit, as cats hate the smell of strong perfumes so much that they will avoid them. Not good if you want them to use the litter tray!
