Hi there, Skye Blake here… searching for biodegradable cat litter for your extra-fussy feline.

There are a lot of weird litters out there… Bamboo, tofu (soy), walnut, corn, hemp, and many more!

Frankly I could make a salad!

The information here is for general knowledge… always see your vet with questions about your cat’s individual needs.

What Is “Biodegradable”?

Any organic matter that is biodegradable can be decomposed by bacteria or other living organisms.

Plants and animals (except bones) are good examples. So cat litter made from plant material is considered biodegradable.

Clay doesn’t break down into the earth because it IS earth, so it accumulates in landfills. There are claims that this is a problem (deserves further research).

Silica litter doesn’t break down either.

Biodegradable litters are good for special situations like after surgery, dealing with kittens, or a fussy feline with asthma or an extra-sensitive nose.

They’re also nice for people wanting eco-friendly litter.

Cat behaviorist Jackson Galaxy has observed that these biodegradable types of cat litter have been improving over time and there are some good quality ones available now.11“The Benefits of Natural Litter”, by Jackson Galaxy

Some behaviorists don’t like food based litters such as corn or wheat.

Cats won’t eat where they do their business, and some eat these grain litters.

Others won’t use it because it smells like food.

It conflicts with their strong instinct to separate where they eat and pee so they often decide to find another place to do their business.

Sometimes cats don’t like how their paws sink down into these litters and that makes it unacceptable to them as well.

You’ll need to be very familiar with your cat’s individual preferences.

Is Biodegradable Cat Litter Flushable?

Some biodegradable litter manufacturers claim it’s flushable… hey, that’s cool!

Flush it all down the toilet… no more throwing it in the trash! But wait!…

Not all plumbing can handle it, septic systems in particular. So be sure to test with small amounts no matter what the claims.

You don’t need a backed up toilet, clogged pipes and a big plumbing bill!

Flushing litter isn’t permitted in some areas so be sure to check your local ordinances.

Biodegradable Litter as Mulch

You can use biodegradable cat litter as mulch on your flower beds, but not directly on vegetable, herb or other edible plant beds.

Cat waste can transmit diseases, but if you process the litter properly into compost, removing possible pathogens, it can be used safely.

If you’re not sure, just put it on flower beds.

Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
