The Green Pee Cat Litter System
Intro: The Green Pee Cat Litter System
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.

Okay, you said: "Stops all the cat litter going into the landfills." What's the problem with cat litter going into landfills? Cat litter is organic. It's either made of clay or wood. It decomposes perfectly fine in landfills. Besides, if you're worried about putting stuff in landfills that don't decompose, then why does your picture show the dirty newspaper sitting inside a "PLASTIC" bag? The plastic bags you use will end up in the landfill. .............. Also, I wouldn't us the gravel because cat poop can be sticky or runny and you can't just pick that up off of the gravel and expect the gravel to be clean. There will be fecal matter still on the gravel for your cat to step on and transfer it to its feet, then the cat gets out of the pan and gets on your furniture, or on the carpet (which if you have a crawling baby on the floor, the baby is touching that cat feces and then putting its hands in it mouth), or your cat gets on your lap. YUCK! No thank you, I don't want cat feces all over my house. Sorry, I'll stick to the clumping litter that is much more sanitary.

Clay is an inert material, but it also takes up land-fill space. The more material we throw into land-fills, the more land we have to clear and convert to land-fill. We certainly aren't at the theoretical re-mine/re-use part of the land-fill lifespan yet. (Unless you count land-fill methane extraction).
Clay litters can also cause silicosis (think asbestosis). Those clays that use bentonite can also cause intestinal distress, as the dust can stick to kitty feet and bottoms, and is ingested when the cat grooms. https://www.jacksongalaxy.com/blog/the-benefits-of...
Wood litters are biodegradable, but you have to ensure that your supplier produces them from renewably managed forests or plantations. Recycled paper pellets are a better option, but don't have the deodorising abilities of wood pellets. The bicarbonate is a good solution for this but is irritating (It's basic, pH about 9) if the cat comes in direct skin contact with it. Again, they also take up land-fill space if not composted, and this has big environmental impacts despite being biodegradable.
I'd love if a system like this could have the bottom tray plumbed in, and the pee flushed out into a black-water line once the cat stepped out of the tray. Add a fan to draw smells down from the top tray (and dry the poop a bit) and you've got something really cool.

This could work especially well for cats fed a raw/meat-based diet. The poo will be smaller and drier, so not very smelly and won't stick much to the gravel.

Great, thanks for the instructable! I can honestly say this has changed my life. No more sweeping up tracked litter several times a day.
I used a pair of tall clear 57l plastic containers (the high sides contain everything but can still be seen through so my cats will actually use it!) and cut an entrance in
one end. The two boxes have lugs so when stacked they leave about 1" for the wee collection. My cats aren't very keen on pebbles under their paws so I used baked clay balls (the ones used for hydroponics). My older cat was straight in it, surprisingly no need for any transition from clumping litter to the clay balls! And there is no more tracking round the house, just a couple of clay balls to pick up if he's been a bit enthusiastic with his digging.
They are a bit dusty straight out of the bag so I give them a good rinse in a collander before tipping into the tray, to stop muddy footprints round the house.
The clay balls have become a little bit whiffy so I'm going to try soaking a batch in diluted vinegar, and will leave another batch outside.

if I lightly dust the clean dry pea stones with Cornstarch, would it reduce rather amount stones sticking to the poo when it's time to scoop? And vice versa...

FYI: tea tree oil is a neurotoxin...do not use it on or near kitty's habitat

Google around, you can buy it in huge bags for cleaning purposes, it's much cheaper. $7 for a few kg.

Baking soda is just about the cheapest thing you can buy. Less than $1 for a 2x4x5inch box in any grocery store.
