Can You Compost Cat Poop and Cat Litter?
Most gardeners will say that you should not compost cat poop and cat litter. The potential dangers from pet waste outweigh the benefits.
That being said, if you are determined to compost your cat’s poop, then it is definitely possible.
Cat poop is an organic material. It contains many beneficial nutrients, including the same amount of potassium and phosphorus as cow manure and over twice as much nitrogen.
However, unlike cows, cats are carnivores, and meat consumption makes their feces less than desirable to add to the compost pile.
The issues with cat poop come from the parasites and diseases that are contained within the poop. Cat poop contains many pathogens that are harmful to humans.
Most types of cat litter are not suitable for composting, including non-clumping, scented, or clay-based litter. Most litter contains chemical additives that are not good for composting.
The only ones suitable for compost are natural, unscented litter made from sawdust or wheat. These are biodegradable cat litter and usually plant-based, so they’re environmentally friendly.
Benefits of Cat Poop and Cat Litter
As mentioned above, cat poop does contain many beneficial nutrients. However, the most significant benefit of composting cat poop is the environmental impact.
Millions of Americans have cats as pets, and a growing number of cat owners are seeing the effect loose cats have on wildlife, so they are opting to keep their cats indoors more.
This creates a large amount of cat waste that ends up inside plastic trash bags and in the landfill. Obviously, it would be better to let your cat’s waste decompose naturally and be a usable fertilizer for your garden.
Dangers of Cat Poop and Cat Litter
The biggest issue with cat poop is that it contains a parasite called Toxoplasma-gondii that causes Toxoplasmosis.
While this infection is usually harmless, it can lead to severe problems for those with a weak immune system and for pregnant women. Composting litter isn’t recommended if you have health issues.
Cat poop can also contain other parasites, like intestinal worms, as well as other diseases. You should always be careful when handling cat poop or litter box trays. Wear gloves where possible, and always wash your hands thoroughly.
If you’re composting cat litter and poop, it’s best not to use the finished compost in your vegetable garden soil. For your edible garden that’s growing edible plants, the potential bacteria and pathogens that could be passed on to your vegetables would not be safe.
How to Compost Cat Poop and Cat Litter
Although many people believe that the dangers of composting cat poop far outweigh the benefits, you may have your mind set on composting your cat’s waste.
Here are the steps to successfully and safely compost cat poop and litter.
1. Choose your cat litter carefully
Only use biodegradable cat litter if you are composting it. This will rule out many popular, cheaper litter – including odor neutralizing and perfumed varieties.
First things first — you’ll want to change out your cat’s litter for one made from natural materials. It could be pellets made from recycled newspapers, pine, corn, wheat, or any combination thereof. These could be called paper litter or pellet litter, or litter made from plant materials.
Pellet, biodegradable litter is less harmful to cats and the composting process. Most clay litter contain silica dust and chemical additives that may be harmful for to your cat’s health.
Bear in mind that if you choose a natural litter, it will smell. There is no way around the foul smell, hence the popularity of odor neutralizing litter.
You basically have two options: get used to the smell of cat waste or change your litter tray at least once every day. This is probably one of the top reasons people give up composting their cat’s feces.
2. Use a separate compost bin for your cat waste
This is my personal opinion, and you will find others who will say it’s okay to add it to your regular composter.
However, I would like to have a separate pet waste compost bin to ensure that I leave enough time for the harmful bacteria, parasites, and diseases to be dispersed before using it as compost.
Some sources say that you can use compost containing cat poop in as little as six months if you use hot composting methods.
Personally, I would not be able to trust that the cat poop will be completely safe in this time – especially if you are using your compost for vegetables.
Cat waste can take up to 18 months to decompose properly, so I say it is worth having a separate bin to rule out any cross-contamination that may occur.
3. Add a layer of brown material every time you add cat poop into your bin
Even if your kitty litter is made from sawdust, it’s good to add a layer of brown materials as well. This can be sawdust, wood chips, soil, or even compost.
They will help your cat poop break down and make the end product better by slowing down the decomposition process caused by the high nitrogen content of the poop.
Nitrogen-rich ingredients are green material, so adding a layer of brown will help balance the compost.
4. Be patient during the decomposition process
WAIT! Time heals all wounds, and any organic material will decompose over time. The longer you can leave your cat poop to decay, the safer it will be to use.
If you have a separate compost bin specifically for composting dog poop and other pet waste, it won’t be too much of an issue waiting for it to decompose.
Many commercially available compost bins have a hatch in the bottom for you to extract the compost. These are the best type for composting cat poop, as you won’t want to turn over this compost. Something like this compost bin being sold online is good.
The longer you leave the poop to decompose, the better, so you don’t want to mix fresh waste with the old. Also, this compost will smell pretty bad while it’s decomposing, so not turning it over will be kinder for your nose!
