Oh no! Please don't declaw!! We had it done to one cat yeaaaars ago... we were new to cats, didn't have the wealth of information that is now available through the internet and other sources. My mom still talks about how she regrets that choice. I was only 8 so didn't have much of a say, but I do remember crying about my cat looking so sad and in so much pain from it.
The way softclaws work is that you trim the nail, put a dab of glue inside the softclaw and then put that on the cat's trimmed nail. The nail will grow, softclaws are not permanent, that is why they must be replaced every couple weeks, more often depending on the cat. They will still stretch out and claw at things, but they can do no damage. Combine softclaws maybe with some training and you should be fine. I think sometimes they look so cute, like the cat has a pedicure!
