Query: Strangely and immediately irresistable to my cats.

Scoop Free LB1 Self-Cleaning Litter BoxMy cats are large - just not Maine Coon large. As far as ordinary domestic cat size, two of my five cats are large. And consequently, I go through the cartridges faster than 2/15 days. Even so, I rate this highly because my cats immediately adapted to using this system without *mistakes.* There is *no* odor or fragrance! I also discovered great relief in ridding my house and myself of the heavy bags of litter and the scattering messes I, the cats, and the hole-y bags had always made.I would change my review to 5 of 5 stars if Amazon allowed at this time.
