This might not work for everyone...some people wouldn't have a convenient place to put it, or no access to wood, but....what about a
real tree branch? Years ago when the arborists were cutting up a dead tree for removal on our street, Carolyn and I both retrieved a big branch for our cats...they love it! Mine has been scratched on by every cat since I got it. This actually lives sort of horizontal to the floor, but had to move it to get a good picture...and Leia came to see what I was doing with her scratching post! It doesn't show up too clearly in the pic, but it's
well scratched! Chancer having been a outside cat might like it....just a suggestion...
