Cat nail caps are covers that can be made from various materials. They're extremely easy to apply; simply glue them onto your cat's nails.  The caps are simple to put on, inexpensive and give your cat a fashionable look. To avoid causing discomfort to the cat, the caps are shaped similarly to their nails.  They are available in a variety of sizes and colors, and they typically last 4 to 6 weeks. Most importantly, claw caps have no adverse effect on the cat's natural nail growth.
