Is natural cat litter really better for my cat?

Natural cat litter

Our cat is a member of the family. While he’s sometimes moody and picky about his meals, he seems to prefer dog food, we want him to be happy and healthy for a long time. To be honest, I never really thought much about our cat litter. I know that I like the clumping cat litter over the non-clumping and what the prices typically run, but I hadn’t considered that there may be things in his litter that are not good for him or us.

I have the opportunity to try natural cat litter from World’s Best cat litter in this sponsored post and thought, why not? What I discovered may surprise you and I’ll share my experience using this with my well-hydrated and well-fed indoor cat. Post contains affiliate links. 

natural cat litter is it really better?

When I read that World’s Best cat litter was made from corn, the first question I asked was whether it was made from non-GMO corn. It is not. I called the company and the representative sent me information about corn itself and details including the fact that 90% of corn is not Non-GMO. So, is this better than my current litter?

The truth about what’s in my current cat litter

I called Tidy Cats, I currently use Tidy Cats with the red lid. I called the company and asked the representative what the cat litter was made from? First, there was a long pause on the phone. I repeated my question. What is my cat’s litter made of? He said “kaolin clay” and stopped. I followed up again and asked, “clay sounds nice, what else is in there?” He took my name and address to mail me a MSDS sheet, or material safety data sheet. Unlike World’s Best cat litter who jumped at the chance to e-mail me info, I had to wait for the snail mail as the Nestle representative said the info was unavailable for e-mail.

So, being the clever person I am with the internet, I googled the sheet for myself and realized why the company rep was reluctant to disclose the ingredients. Turns out, there is more than clay in my cat’s litter. Other ingredients include quartz, calcite (calcium carbonate), gypsum (calcium sulfate),  Opal CT (as amorphous silica), Diatomaceous earth (uncalcined), Illite, Montmorillonite & Feldspar. (1)

Aside from my concern about the mining processes used to obtain some of those ingredients, I am not sure what I’m looking at. Then, I arrive at the “health hazards” section of the MSDS sheet. It says ” Dust can be irritating to skin, eyes and nasal passages…Crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans. Dust may irritate nasal passages.”

What does this mean for my cat’s health?

ACUTE: Dust may irritate nasal passages.
CHRONIC: Prolonged and repeated exposure to free silica may result in silicosis, a form of progressive pulmonary fibrosis characterized by impairment of pulmonary function. Onset and progression are related to dust concentration and duration of exposure. (1)

After reading this I immediately feel bad for subjecting my cat to this litter and am now aware of why a cat I had previously was chronically ill. He went from veterinarian to veterinarian with a skin rash…was tested for medical conditions that always came up empty…no one ever thought about the cat litter. I never thought to switch to a natural cat litter.

What’s in natural cat litter specifically World’s Best cat litter?

So, opposed to what I listed above, the cat litter we are testing out is made from corn. Now, as I mentioned above its not non-GMO corn, but it’s also not a chemical shit storm that will give my cat respiratory issues and possibly skin irritation. Zero of the items I listed above, in my current cat litter, are present in World’s Best Cat Litter. None.

So, what about the corn?

The World’s Best cat litter is proud of their ingredients and was happy to send me ample info about their corn. They said, “Although World’s Best Cat Litter™ is not a food product, it is made from the same corn used for animal feeds, human grade food products, and pharmaceutical products in the U.S.” Great right? Take a look at my sample bag below:

    • The state of California encourages the disposal of cat feces in trash and discourages flushing feces in toilets or disposing of them in drains. I personally am not flushing this because our septic system is super old and finicky. 
  • Actually, works. My husband said, “wow, this clumps better than the other stuff.” We were using Tidy Cats multi-cat clumping.

Downsides to natural cat litter?

The only downside I can see is that this is more expensive. The clumping litter I use now is more expensive than the non-clumping and this formula is more expensive than both. However the major upside, it isn’t full of chemicals or the ingredients I listed above that reportedly can cause skin and respiratory issues. This will make this a must-have for some pet owners. I can see this being especially beneficial for cats, or cat owners, with health issues or sensitivities.

I feel the same about natural products. I wish they weren’t so expensive. I wonder if the potential reactions cats have to litter affect humans as well?

We love this litter and won’t use anything else. If you live near an ocean or waterway though toxoplasmosis can be transmitted to the ocean and be harmful and damaging to sea life, especially otters. It is suggested not to flush cat feces or urine if close.

Actually, Natural litter is cheaper than clay litter. Natural litter lasts longer than clay. Using the standard recommended 3″ fill in a litter tray…you need 25# of clay versus 10-11# of natural litter. Therefore, it costs about $11 to fill a tray of clay litter and a little less than $10 to fill a tray with natural litter.
