the catgenie is pricy. the supplies are pricy. not having to clean a litterbox though - that is priceless. i will never go back to a classic litter box.
i will spend months w/o even checking on the catgenie. it is smaller than some other litter boxes, and cats generally do not enjoy the shallow litter pan, but having a clean litter box every time they go - that to them is priceless. i don't believe they would want to go back to a classic litter box.
and on a side note - the customer service is outstanding.
