I used Soft Paws on my cats about 8-9 years ago, when they first came out. I thought the idea was awesome. However, my cats would chew and pull them off, hurting their claws and the surrounding area. In hindsight, I wish I would have never have used them. I only used them for about a 6-7 months, and to this day, they are still sensitive around some of their paws.
I hate to put a damper on what could be a great solution, but know this is a possibility, so you can decide what is the best thing to do.
I ended up getting a tendonechomy (probably butchered the spelling of that!). I wished I had done this first INSTEAD of putting my babies through the experience with the Soft Paws - especially since it's had such a long term affect on them. The procedure is a tiny incision and they cut the tendons in the paws so they can't use their claws. It requires no stitches (just a dot of glue), and both cats were running around in no time (my oldest is only 6 pounds, and she was running around by the next day). All you have to do is trim their nails. They can't scratch a thing, and it's worlds apart from de-clawing.
I have heard of a couple of vets not supporting this, but let me tell you from my experience, they are CRAZY. My cats would have been in a MUCH better emotional and physical state, if I had not put them through the 'torcher' of the Soft Paws. Check it out, and if you're vet doesn't support it, they don't know enough about it... find ANOTHER vet. It really is the most wonderful procedure, with the least amount of impact to your cat.
Best of luck to you!
