Keep lovingly tended borders free from cats and the mess they cause. The pellets are soaked in real essence of lion dung dried and sterilised. As cats are territorial even the bravest will retreat when they smell a lion. An environmentally-friendly product which contains no artificial chemicals. One application can last up to three months during normal weather conditions. Always handle the pellets with gloves - the pellets are not harmful but if you let human scent contaminate the pellets, the local cats may be less wary. Although Silent Roar has been recognised as a successful cat repellent for many years, EU regulations mean that it can now not be officially classed as such although it remains exactly the same product.
