Can anyone tell me if there is a particular type of carpet that would be
 best for applying to a scratching/climbing post.

Thanks,
Bill

I'd wrap it with carpeting that is a different texture than what is on your
floors. I'd recommend wrapping it with some sissal rope as well so the cat
has a choice (2 of my 3 seem to prefer the sissal). I'm guessing here, but I
figure if the texture on the scratching post is different than what you
don't want them scratching on they may have an easier time telling the
difference. Someone else may have more scientific advice.

It really doesn't matter. Berber seems to snag worse. We make cat trees, and
find that a middle-grade plush best, it''s thick enough to be more durable, but
not so thick that it's still pliable. Ours like sisal rope,, too. We generally
just go with whatever remnants we can find. Sometimes, (on the cat trees) we
use upholstery material--it's not as durable as carpet, but much easier to
replace when it's worn. You can "match" your own furniture that way, and I
think helps give an alternative to the cats who just like to claw the furniture
particularly. Good luck! You may get hooked like we did, and end up with cat
trees/scratching posts all over the place.
