Disposing of kitty litter can be a complicated issue, fraught with many environmental concerns. This is especially true, if your kitty litter has clay in it. When it comes to clay, just the mining process alone, wreaks havoc on forests, vegetation and wildlife. 

So, if you’re endeavoring to be more environmentally conscious, you may want to think about a biodegradable option. Furthermore, if you’re looking into biodegradable litter options, you’re probably asking yourself the question, “Can You Compost Cat Litter?” In that regard, below is a brief explanation, as to how cat litter can be composted. 

Is Cat Litter Biodegradable?
The first thing to be aware of, is that clay cannot be composted. So, if you’re serious about composting, you’ll need to find a biodegradable litter option. The following is a list, that can give you a starting point, on finding a proper biodegradable litter for your cat.

Grass Seed
This is considered to do a good job controlling odor. Dust doesn’t spread, but you’ll need to clean-up around the box, because the seeds can get caught in a cat’s toes. It also clumps, which can help with scooping.

Newspaper seems to be a popular choice. Probably because it’s so readily available. You may have issues with it controlling odors, but not all cats are alike, so it may work for your cat.

Wheat is a highly regarded alternative, however, you might have issues with your cat tracking it around.

Pine Cobble
Reportedly cats are naturally drawn to this renewable pine option.


The above list of materials are all naturally biodegradable—clay is not.

Compost Cat Litter
So, now that we understand, that clay cannot be composted and that the above biodegradable litters are an ideal choice for natural disposal, let’s talk about how to compost.

  1. Be sure that the cat litter you use is biodegradable. See the above list for ideas.
  2. Scoop out the waste and place it in a biodegradable bag.
  3. Put the rest of the litter into the compost pile, nowhere near growing food.
  4. Make sure that all litter is scooped and disposed of in a biodegradable bag.
    If you can’t do this for whatever reason, then don’t let it get near anything edible.
  5. Also, don’t compost near any water supplies.
  6. It’s critical that you don’t let the waste get near any food or drinking sources.

Litter Disposal That’s Eco Friendly
It’s not advisable to flush the litter waste down the toilet. The local water treatment plants, generally can’t treat the pathogens and bacteria that’s contained within the waste. If you must insist, at least call the water treatment plant first, to see if they can treat cat litter waste. That way you can be sure. However, below are to other options to naturally deal with litter disposal.

  1. Compost. This is considered the best option. You just have to separate the cat waste from the litter. If you do decide to leave the cat waste in with the litter, you have to be sure that your compost heats up to and over 145°F. If this is not possible, then just scoop and toss it.
  2. Scoop & Toss. This is considered the lesser of the two options, but it’s one of the best choices available. Simply scoop it into a biodegradable bag, then toss it into the dumpster. Every thirty days, when you change the litter in the box, you can empty it into newspaper, then wrap it up and throw it in the dumpster.

In conclusion, more and more cat owners are becoming environmentally responsible. If you’re a cat owner looking to do your part to make sure your litter box routine is eco-friendly, then the above info is a great place to start. Thanks for reading “Can You Compost Cat Litter?”
