DECLAW or not DECLAW, That is the question.

I'm at a cross roads with one of my cats. Her name is Sophie and she might weigh 8lbs soaking wet. She's a very loving cat but she is wreaking havoc on my furniture.
I have tried just about everything so far and nothing seems to work on her.
We have purchased several different scratching posts, card board scratching stands, sprays, tapes, tinfoil, squirt guns, squirt bottles, clapping my hands together, yelling, praying, etc...
It doesn't matter what is next to her. If she gets the urge to scratch and claw, god help the object that is next to her.

So as you see, I'm at my wits end with Mrs. Ninja Kitty and she is one step away from getting declawed. I REALLY do not want to do this as I agree with masses that it will hurt her and change her attitude. So, I am going to try some form of nail caps and see how that goes. I will keep you posted and let you know how this turns out. If any readers have used this technique before please let me know how it worked for you.
