The spray is supposed to be best for the scratching, but I did some reading, and I guess it's best if you have the plug-in Feliway diffuser, too. So I bought that on eBay yesterday. The only problem will be finding an outlet for it.

I hope that the Feliway helps us both.

Trimming their nails regularly is supposed to help, too. I guess you are supposed to do it every 2 weeks or so, but I don't keep up with it like I should.
