Soft Paws is an effective, safe and humane alternative to declawing! Your Cat will love you for it! Each Soft Paws kit contains 40 nail caps, 2 tubes of adhesive, applicator tips and easy to follow instructions. One kit contains enough for 4 front paw applications. Each application lasts approximately 4-6 weeks therefore each kit lasts approximately 4-6 months. Note: While the vast majority of cats acclimate to the claw covers within minutes, some cats may require an adjustment period. Cat's fastidious natures sometimes causes them to groom the claw covers excessively at first. This may result in one or two falling off. No problem. Just check the claws daily at first and if one is missing, simply replace it with another from the package. Thus, the first package may not last as long as subsequent packages. Again, most cats do not even notice they are wearing them after the first 30 minutes. Soft Paws can also be safely used on Ferrets. For Ferrets, use the kitten size.
