I got the word from my g/f that the cat litter box had to go. She bought me the tuxedo edition with all the bells and whistles for Christmas in 2011. I can't believe it, I haven't touched litter in a year. I LOVE it. We had two cats at the time, and now we have the same two and two Savannahs that she got me for Christmas this year. (personally, I think she got them for her) and the cat genie is still the best. Even for all 4. We do the super clean a little more often, but it is SO worth it. Just needs something to get the granules out of their feet before exiting.
