answer:There is no cheap natural solution that I know of other than toilet training. IMO, you either invest in a whole system like the Tidy Cat thing I use. Or you do what I used to do for one of mine that can’t use the potty which is put a plastic bag in the litter pan & use a newspaper pellet and toss the litter out daily. OR, you Toilet Train: I have one cat that uses the toilet. She’s the cleanest and most natural of all. How old is your cat? Do you have an extra toilet you could train it on? If so, here’s a site that’ll teach you how it’s the site I used to train two cats with…it worked and cost me very little in money or supplies However, two of my cats will not go on the toilet, so I use the Tidy Cat Breeze system for them.
