PHEROMA Litter Powder is a product of recent research into the nature of smells. Available in Spray and Powder forms, it is a pet odour remover based on a new scientific principle. It can successfully be used on bad smells such as cat urine, anal gland smells, cat litter, vomit, faeces - and even sour milk. Most other products simply mask the unpleasant smell with a strong perfume, leaving the underlying malodour to return when the perfume evaporates. But PHEROMA actually removes unpleasant odours permanently. It is completely safe to use. Use the pleasant-smelling powder form for litter trays or use spray for carpets and furniture. Just one spray or sprinkle and your environment will once again smell as fresh as a daisy.
