Not just yes, but enthusiastically (and glassy-eyed) yes!
I keep the catnip plant in a hanging planter in the tree. My tomcat's favorite treat is when I hold him and stand beside the plant so he can eat some of the leaves. He absolutely loves that.
Last year, I made the somewhat unwise decision to set the plant on the ground for a couple of days . . . that was nearly the end of that plant. However, the cats laying out there and rolling all around, etc., was amusing.
I am thinking of planting some at the chicken pen to encourage intruding cats to linger there and catch any stray mice. A bird cage over the catnip plant will protect it while letting the cats savor its aroma and extruding leaves. Somehow, a birdcage protecting the plant seems more appropriate than a wire cage made for that purpose. Maybe some clever cat can figure out how to open the door and get more delightful catnip.
