I purchased the Model 120 catgenie about 6 months ago and I haven't had to fuss with kitty litter since. With only the occasional change of scent cartridges and the addition of additional granules, it has almost been a hands-off item. The catgenie is down in the laundry room and my 2 year old cat immediately took to it and has loved the fact that she always is using a clean box. Nothing to dirty her dainty paws. I have it set to twice daily and this has been sufficient to keep up with her needs.
I had been skeptical about the product as I had used other "automatic scooping cat boxes" which still required handling containers of foul smelling clumps, changing kitty litter, and always having to buy the premium brand litter. How could this really be self flushing and fuss free? However, the product worked even better than I could imagine. Thank you for making such a great product. My husband, cat, and I thank you.
