I use Soft Claws and highly recommend them as an alternative to declawing. They are a learning experience. Whenever I have someone interested in a kitten that mentions declawing, I slap on a set and educate them. Here's a few tips I give my adopters:
1.\tDon’t get frustrated. It takes practice. Cats are unbearably stubborn and resistant to change. It may take you a week to get on your first set of Soft Claws and that’s okay. I actually never attempt to put on a full set on a new cat in one sitting. Put on one at a time and let him/her get used to the idea.
2.\tBe prepared for your cat to act as if you have just put it through horrendous torture! After application it’s antics in an attempt to remove the Soft Claws will probably make you laugh. This is only temporary, so don’t despair. Some particularly tricky cats even manage to remove a cap or two. They do stop attempting with repeated application.
3.\tGlue. I have found that the best super glue to use when applying Soft Claws is NOT the glue provided with the nail caps. I buy 3m Super Glue Gel, which is MUCH STRONGER and helps prevent the caps from falling off or from the cat removing them on their own (see tricky cat reference above).
4.\tDepending on why you’re applying Soft Claws, you might consider only applying them to the front paws. This allows the caps to last you much longer (4 – 6 months).
5.\tAfter you fill the cap with the super glue, take a needle, stick it in the cap and rub the glue around to ensure the whole area is covered. This helps surround the entire inside of the cap with glue, removing air bubbles and helps ensure the caps stay on. (This whole process really doesn't take as long as it sounds!)
6.\tIt helps to have one person hold the cat and one person applying the Soft Claws. The cat needs to be held for about 60 seconds for the glue to dry after applying the cap. If you are attempting this alone, I suggest wrapping the cat in a towel and straddling it between your legs. No, the cat will not be happy.
Kittens are by far the easiest. I hunt them down as they sleep and apply them. Ditto, my youngest Siamese is a terror to put them on, but he almost preens after they're all on. It's hilarious. I use the the clear and colors, whichever I have available.
Here's Ditto with the blue nails that match his eyes.
