The Green Pee Cat Litter System uses a non-porous filler, pea gravel in a perforated tray sitting in a second tray that contains an absorbent layer of newspaper with baking soda.
The cat urine flows through the non-porous pea gravel into the second tray where it is absorbed by the news and the odors are neutralized by the baking soda.
All you have to do is scoop out the solids from the pea gravel once a day and change out the newspaper and baking soda once a week.
Once a month or so you change out the gravel. The gravel is hosed off or dumped outside where the rain cleans it and it can be reused.
My cats had to be trained to go on the gravel.
I put regular cat litter on one side of the box and pea gravel on the other side.
There was some mixing of the two as the cat used the box.
Then I gradually used less litter and more gravel.
Now my cats use the new system with only pea gravel and my life is a little easier
Green Pee Cat Litter System is green because it:
1- Stops all the cat litter going into the landfills.
2- Saves the cost of buying cat litter.
3- Recycles newspaper.
4- Saves time changing out cat box.
5- Helps control odor.

I hooked a hose to the funnel of the the bottom tray and attached the other end to the down drain to sewer. Very easy to do.
I also put one in a bedroom, but have it draining outside to a gallon jug with holes to the flower bed. I add water to dillute the urine.
You can buy plastic pellets to use instead of the seeds.. its cleaner than the seeds, and less expensive, and faily easy to clean. I was them with vinegar.
Also, you can just put the setup on plastic stand, drill a hole in the top of the shelf and funel/tube it to a one gallon jar with about an inch of vinegar in it. Works great. This is how i did it for testing. Do not pour this on anything you want to live outside, the vinegar kills it.
I am wondering if aquarium filter pellets (activated charcoal) would help with odor.
DO NOT however compost cat poo. It has [pathogens in it. You can dig a trench 6 - 8 inches below ground and put it in there and it will eventually decompose and keep the pathogens out of the top soil layer. DO NOT put the trench near fruit trees or vegetable gardens.
Cheers.
Remember, feral cats (who are the most likely carriers of toxoplasmosis) are just wandering around pooping wherever they want. It doesn't get composted. As long as you follow good-sense precautions, composting cat waste is totally safe.
The pine will make the garden acidic for about a year so you might want to put it in a compost heap to rot a little first.
My garden last year was "fried" from the pine - only 2 litter boxes worth! the soil was so hot that only one plant did much the rest were just leaves.
Hopefully this year will be better.
This is a wonderful idea - I'll definitely be trying this out. I've been putting newspaper in the bottom of the box for years as a bottom absorbent layer.
re: smell, i found a product called Anti-Icky Poo that works really well, and comes highly recommended.
re: self cleaning litter boxes, i have several complaints. my husband bought one and our cat's back paw was sliced open, resulting in infection, renal failure and over $1000 in vet bills. she's ok, but now on modified kidney diet. also, the cartridges don't lock in properly, so litter ends up underneath the thing and you have to clean up much more than you normally would. there are several nooks & crannies that catch litter and need to be cleaned out. you can only use certain litter. the stuff that comes with it is corn based, but the cartridges aren't reusable and the thing requires electricity, hardly what i call "green."
