Developed by a veterinarian, Soft Paws nail caps are made in the USA using non-toxic vinyl. The nail caps are applied to your cats claws using a non-toxic, cold-bonding, veterinary-grade adhesive, and are a completely safe and humane solution to cat scratching problems. Soft Paws do not interfere with the normal extension and retraction of claws, and most cats don't even know they are wearing them.Contains 40 nail caps, 2 tubes of adhesive, applicator tips, and instructionsHumane alternative to declawingDeveloped by a veterinarianMade in the USA with non-toxic materialsDoes not interfere with normal claw extension and retractionSoft Claws Nail Caps Sizing Guide:Kittens - Up to 5 lbsSmall - Cats 6-8 lbsMedium - Cats 9-13 lbsLarge - Cats 14 lbs and up
