Our changeable and replaceable De'Vora Kicks Nail Trimming Kit provides pet parents with an easy and effective way to file and trim their pet's nails. Each set of Kicks includes three pairs of different grits: Coarse, File and Smooth. To achieve the best results, we recommend allowing your pet to scratch through the roughness sequence, starting with the Coarse grit and progressing to the File and Smooth surfaces. This will help keep your De' Vora grooming toy in top condition for future use. The Kicks' smooth surface is specifically designed to support daily use, ensuring that your pet's nails are kept smooth and healthy. Please note that our Kicks are sold exclusively for use with Scratch Square by De' Vora, ensuring a perfect fit and optimal performance. It's made with natural garnet abrasive minerals, ensuring safe and effective nail filing. It's also designed to give pet nails a smooth and healthy finish, reducing the risk of scratches and other nail-related injuries.
