Best Method for Declawing a Cat?

Although I am against it, a new and rather expensive leather sofa has
raised the possibility of declawing my 3 cats.

If I have to get them declawed what is the best way to do it?

What kinds of questions should I ask the vet? What kind of equipment should
he have/use?

Simply declawing their front paws may not accomplish much with regard to
protecting the furniture.


Also, I am going to ask in a separate thread:

If I keep my cats nails trimmed short will they still be able to
(unintentionally) damage my leather sofa?
