Digging Through History: Unearthing the Origins of Cat Litter

Cats have a deeply ingrained habit of hiding their waste, but it’s not just about cleanliness for them. Live Science explains that this behavior is rooted in their long history and the strategic use of urine and feces to claim territory. For cats, each poop is unique, carrying chemical scent markers known as pheromones. These allow them to distinguish their waste from another cat’s, which is critical in their communication.

In the wild, the hierarchy among cats plays out through their waste disposal habits. The big cats of the Panthera genus – lions, tigers, leopards, and jaguars – often don’t bury their excrement. This acts as a bold declaration of claiming territory. On the other hand, smaller or more timid wild cats conceal their feces as a gesture of not challenging more dominant ones. Besides territorial matters, hiding waste helps wild cats steer clear of predators, protecting themselves and their young.

Historically, cats were drawn to soft surfaces like dirt or sand for burying their waste due to its easy-to-dig texture. This preference has carried over to modern indoor cats and the litter their owners provide. The evolution of cat litter began in the late 1940s when bringing cats indoors became more common due to outdoor safety concerns. Initially, cat owners used ashes, sawdust, soil, newspaper, or sand as make-do litter solutions. Understandably, these materials were far from perfect – they left dirty paw prints everywhere and did little to contain odors.

In 1947, Edward Lowe transformed the cat litter industry. According to Disposable America, while working with his father selling sand, sawdust, and clay to industrial companies in South Bend, Indiana, he stumbled upon a novel use for absorbent clays. When Kaye Draper, either a friend or neighbor, sought a suitable cat pan filler, Lowe suggested using Fuller’s earth clay from his inventory. This type of clay stood out because it was better at soaking up moisture and odors and didn’t spread around the house as easily as other fillers.

Since then, cat litter has evolved significantly from its humble beginnings of sand, ashes, or even dirt. The introduction of clay pan filler is so significant that some believe it directly contributed to increased cat ownership. It marked a turning point, offering a more convenient and effective way for cats to do their business indoors.

Then came a breakthrough in the 1980s when biochemist Thomas Nelson introduced clumping clay litter. This type of litter was revolutionary because it was made from calcium bentonite clay, which could clump together when wet. This meant urine could be easily scooped out without replacing the entire pan’s contents, preventing the breakdown of urine and, thus, significantly reducing the unpleasant smell of ammonia.

Despite its convenience and effectiveness, clumping clay litter raised concerns regarding its environmental impact and health risks. The primary worry revolves around the sustainability of mining the clay, the litter’s non-biodegradable nature, and the dust it generates, which could be harmful when inhaled.

These concerns have spurred the development of eco-friendly alternatives. These options aim to offer the best of both worlds: they are gentle on the environment while still providing excellent odor control and easy maintenance. Today, eco-conscious cat owners have many options that prioritize sustainability without compromising performance.

The Scoop on Biodegradable Cat Litter: Why It’s a Better Choice

Biodegradable cat litter offers numerous advantages over traditional clay litter. One of the primary advantages is its capacity to minimize environmental impact. This is accomplished as the litter breaks down naturally over time, significantly reducing the accumulation of waste in landfills. 

Moreover, most biodegradable litter options are manufactured using renewable materials, which serves to decrease their overall carbon footprint even further. This contrasts sharply with the current U.S. market, where approximately 60% of cat litter sold is clumping type, predominantly made from bentonite clay. The sourcing process for bentonite clay is far from sustainable, involving strip mining—a method that strips away vegetation, trees, rocks, and topsoil to access the clay below.

Similarly, silica-gel-based or crystal cat litters also present sustainability concerns. As reported by Earth.Org, this variety of cat litter is derived from quartz sand, a non-renewable resource that necessitates mining for its extraction. The production of silica litter is notably detrimental in terms of carbon emissions; manufacturing a single ton of silica gel requires about five tons of coal, resulting in a carbon dioxide output approximately ten times greater than that of other cat litter types.

In addition to their eco-friendly attributes, biodegradable litter products often exhibit superior odor control and clumping capabilities. These ensure that your cat’s living area remains clean and pleasantly fragrant. Therefore, the utilization of biodegradable litter represents a responsible choice for the planet and promises a superior hygiene solution for pet owners seeking to maintain a fresh and inviting home environment for their feline companions. 

Considerations When Purchasing Biodegradable Cat Litter

When it comes to purchasing biodegradable cat litter, there are several important considerations to keep in mind to ensure you’re making the best choice for your cat and the environment. Here are some considerations to help you navigate the process:

  • Material Composition: Consider the material composition of the litter. Opt for natural ingredients like corn, wheat, wood, or coconut, as these are renewable resources and are more likely to be biodegradable. Avoid litters that contain synthetic additives or fragrances, as these can be harmful to your cat and the environment.
  • Clumping Ability: Look for a litter that has excellent clumping ability. Clumping litter makes it easier to scoop and remove waste, leading to a cleaner litter box and a fresher-smelling home. Ensure that the litter forms tight clumps that are easy to scoop out without breaking apart.
  • Odor Control: Odor control is another crucial factor to consider when purchasing cat litter. Choose a litter that effectively neutralizes odors to keep your home smelling fresh. Look for litters that contain natural odor-absorbing materials like activated charcoal or baking soda for maximum effectiveness.
  • Dust Levels: Pay attention to the dust levels of the litter, as excessive dust can harm both you and your cat’s respiratory health. Opt for low-dust or virtually dust-free litter to minimize airborne particles and mess.
  • Environmental Impact: Consider the overall environmental impact of the litter. Look for certifications or labels indicating that the litter is biodegradable, compostable, or sustainable. Avoid litters that contain non-biodegradable materials or are produced using environmentally harmful practices.
  • Flushability: If you prefer a litter that can be flushed down the toilet, ensure that it is labeled as flushable. However, be mindful of your plumbing system’s capabilities and any local regulations regarding flushing cat litter.
  • Compostability: Another eco-friendly option is compostable litter. These litters are designed to break down naturally over time, making them suitable for composting and other organic materials.
  • Tracking: Choose a litter that minimizes tracking to keep your home clean and free of scattered litter. Look for litters with larger granules or special formulations designed to reduce tracking, preventing litter from being carried throughout your home by your cat’s paws.
  • Cat Preferences: Lastly, consider your cat’s preferences and needs. Some cats may have sensitivities to certain litter materials or textures, so choosing a litter that your cat finds comfortable and inviting is essential. Experiment with different types of litter to find the one that works best for your furry friend.

By considering these factors when purchasing biodegradable cat litter, you can make an informed decision that benefits your cat and the environment. Choose a litter that meets your specific needs while prioritizing sustainability and eco-friendliness.

Ensuring Safety When Using Biodegradable Cat Litter

While biodegradable cat litter is generally safe for cats and the environment, it’s essential to follow best practices to ensure your and your pet’s well-being. 

  • Monitor Adjustments: Pay close attention to your cat’s litter box habits after switching to biodegradable litter. Ensure they are comfortable and adjusting well to the change.
  • Maintain Cleanliness: Keep the litter box in optimal condition by scooping waste daily. Regularly replace the litter to maintain cleanliness and control odors effectively.
  • Watch for Allergic Reactions: Be alert to any signs of allergic reactions or sensitivities your cat might display toward certain biodegradable materials, such as corn, wheat, or pine.
  • Pregnancy Precautions: For pregnant individuals, extra care should be taken when handling cat litter due to the risk of toxoplasmosis. It’s advisable to: (a) wear gloves when cleaning the litter box to minimize direct contact; (b) consider delegating this chore to another household member; and (c) wash hands thoroughly after handling cat litter, even if gloves were used.


Opting for eco-friendly and biodegradable cat litter is not only beneficial for the planet but also for your beloved feline companion. By choosing sustainable options offered by eco-friendly cat litter brands, you’re reducing your ecological footprint while providing your cat with a safe, clean, and comfortable environment. With many options available, there’s no excuse not to switch to a ‘purrfectly’ green cat litter.
