Before you have a kitten's claws (and by the way, it's just not the claws, they cut off part of their paws too), if there is a very valid reason you feel you need that safety, there are other avenues you can follow to obtain the same results.

You can purcase a product, soft paws, pretty paws, that are basically plastic false nails that are glued right over the cat's natural claws.

They are safe, humane, last a long time (just glue on new ones eventually) and with them a cat cannot harm anyone or do any damage since there is no sharp edge.

Please consider other alternatives. Declawing is very inhumane, it can affect a cat's personality, and then limits you to keeping the cat indoors, getting another undeclawed cat, and makes it harder to find it a home if that situation becomes necessary.
