This is a product called Soft Paws. These are essentially little plastic caps that are safely glued over the tips of your cats' claws. They stay on for a couple months at a time depending on the cat. The application is slightly involved and is best done by making an appointment with your veterinarian. The cats' claw is trimmed slightly and a small cap with a safe adhesive is placed over it. After a few seconds, the claw is covered and there will be no more destruction to your furniture making this a great alternative to having your cat declawed. These do need to be replaced from time to time but one package contains 40 caps, so it has several uses. Plus, they come in many colors so there are several options to chose from!
