DQ we have very nice leather in the library and the family room. We did a great deal of research because of the two cats and found that leather is a GREAT option with animals (ease to clean etc) IF you put some cash into your purchase. It's not a matter of color, but instead it's the finish. You need to purchase natural leather (which can be dyed but is died throughout the hide) and not buy leather with a shiny finish on it. Yes the cats scratch when they jump around (they have back claws only) but the scratches polish out every easily. We have three leather sofa's, red and taupe, and they look great all the time, plus people can sit on them without leaving with orange hair all over their butt which they did when getting up from my antique sofa (mohair).
I would never declaw a cat again...too much suffering, and I'd NEVER declaw an older cat (mine are six as well) but you can try the tips. My guys chewed them off in about 3 days
but I have heard of folks who kept them on longer. And yes, they do come in colors LOL so it's a true pedicure
I don't bother with the tips anymore, we just polish up the leather when necessary. Downside to natural leather is that wine can stain it, so you have to weigh your sins...scratches and cat hair or spills? We decided red couches would handle the wine issue
