I ordered the Tuxedo Package, dome with door cover and litter mat. It took about one month for my cat to switch from her litter box to the Catgenie. Soon after I fell and broke my arm and this was a life saver as far as keeping up the litter waste. My only complaint is the Washable Granules still get all over the place even with the dome and door cover. Other than that, it is worth the price and time saver.
