get a cheap, mechanized squirt gun for the living room cofcee table. When kitty claws, squirt her. She won't like it and will run away (read as: will stop clawing the recliner). Eventually, the sound of the gun alone, even if the thinv has no water in it, will make kitty stop. Eventually all you will have to do is look at the squirt gun and kitty will behave. This worked very well for my brother and SIL.

Do not declaw the cat... cats need their claws.

Excellent advice...that works for naughty dogs also. Comes the time they only need to see the bottle and off they run. Then comes the time they associate the act of scratching itself with the coming shower, and stop altogether.
I had a dog that would insist on jumping onto the outdoor table. A few squirts and he stopped.

Did you add perfume to the squirt gun with which you squirted the SIL and brother? My ex-brother-in-law would not have taken being squirted, not for a minute!
