Review on 🐱 JSPYFITS Cat Natural Sisal Rope 7mm: Premium Durable Unoiled Twine for Repairing, Recovering or DIY Scratchers. 100% Twisted Thicker Fiber Hemp Rope for Cat Trees and Towers by Robert Lodge

We have several cat trees and they all have this sisal rope on vertical bars. Some are high and some are low. We see that cats only scratch at high poles. Surprisingly, 98 feet is really enough to wrap a tall pole and a short pole. However, short ones do not scratch and do not need to be replaced. I have quite a bit of rope that cannot be used. We used a combination of a hot glue gun and Elmer's glue to hold the rope in place. Smear the cardboard tube with Elmers paint and then use a glue gun to glue it after so many wraps. The cats are already working on it, so it has their seal of approval. Based on local pricing, that's 7mm x 98ft for $18. At Home Depot they are ⅜" x 100' for $23 and ¼" x 100' for $12. It's 7mm or 0.27 inch, so actually closer to ¼ inch. So it's a bit more expensive.
