Automatic Litterbox Central

I had two cats, one who would use LF, and one who preferred anything but LF (the floor, laundry basket, plants) I've tried on and off for over a year...just about everthing. But this month I found the answer. PETSMART SELLS A CATNIP SPRAY. I just sprayed it into the box every day (after manually washing litter). It attracted my kitty, and he loves the box now! FREEDOM. Now if i can just find the products.

Was it the Kookamunga Catnip Spray? That's the only thing I could find on their site.
