Litterbox.com Spray Catnip, 1-oz bottle

I've been trying to get my younger cat to avoid scratching door trim that doesn't involve an eyesore like taping aluminum foil over it. After going through two expensive "anti-scratching" sprays that did little more than spraying water on the trim would have done, I remembered I had a bottle of this sitting around and sprayed it on one of their scratchers. As you can see, a few sprays and she starts rubbing and scratching it. I've noticed her using the posts more frequently (even if it hasn't been sprayed recently) though she hasn't broken her old habit completely. Seems expensive for what it is, but I've used my current bottle a few months and it still feels full. It's also a lot cleaner to use than regular catnip. I tried that on the post before and it obviously falls to the bottom, making a mess I have to sweep. I've started to use the sprays on their toys too for that reason.
