I got both cats using the cat genie within a week or so. The one is still a little weirded out about the noise when cleaning so he will wait around the corner until he hears it turn off. lol. The bundle is great for the money and timed perfectly so I don't need to worry about running out of litter or solution. My only regret is that I did not select the scented one. It is very light and the slight floral makes any slight smells go away instantly. Overall great to just set up the purchases and not need to worry about it!
