Conventional cat litter ingredients

The main ingredients in most cat litters are different kinds of clay, such as sodium bentonite or calcium bentonite. Clay is used because it is an effective liquid absorbent and it can expand up to 15 times its original volume. When it is soaked, it forms clumps which can be scooped easily. It also eliminates urine odour since it separates it effectively.

Another common ingredient in cat litter is silica dust. Similar to clay, it is also used due to its absorbing capacity and odour control.

Why is conventional cat litter harmful?

1. It is bad for the environment

Sodium bentonite clay and silica, the most common ingredients in conventional cat litter, are mostly obtained by strip mining (or surface mining). In order to excavate them, the vegetation and topsoil in the mining area are completely removed. This process is unsustainable and severely affects the environment. It damages the landscape, wildlife habitats, it leads to deforestation, land erosion, and water and air pollution.

Once clay-based and silica-based cat litters are used and then thrown away (as they are not flushable), they end up sitting in landfills for thousands of years since they degrade very slowly, thus adding to the problem of waste accumulation.

2. It is bad for our health

Strip mining does not solely harm the environment. Studies show that people who live in heavily mined areas are at a greater risk of respiratory diseases and lung cancer. You and your pet are not completely safe at home either. Sodium bentonite, which your cat might accidentally ingest while cleaning itself (or eating the litter), may cause intestinal blockage, and other gastrointestinal issues.

Silica dust, commonly found in conventional cat litter, can cause a serious respiratory condition when inhaled and accumulated in the lungs of both humans and cats and is a known cancer-causing agent.

Also, some fragrances and odour neutralising additives in cat litter may be toxic and cause allergies or respiratory issues.

Eco-friendly cat litter alternatives

Now that the ’eco paw-lice’ has detected who the bad guys are, let’s look at the good guys. In order to qualify as a ’good guy’, an alternative to conventional cat litter should be sustainably sourced and free of toxic chemicals, fragrances, bentonite clay and silica dust. Of course, it needs to be a good absorbent and capable of preventing odours as well.

Eco-friendly cat litters can be made of wood, pine, paper, corn, walnut shells, wheat or grass. Also, depending on your cat’s preference and yours, there are clumping and non-clumping types to choose from.

We have done some research for you and made a list of 10 best eco-friendly cat litters.

1. World’s Best Cat Litter Multiple Cat Unscented

This brand’s granules are made from compressed whole-kernel corn. It is free of harmful chemicals, additives and perfumes and contains wood fiber for better odour control. It neutralises the ammonia scent very efficiently and it is easy to scoop as it clumps quickly.

It is 99% dust-free, so it will not pollute the air in your home. One nice fact about the company itself is that it donates litter to cat shelters.

  • Controls odour efficiently
  • Easily cleaned up
  • No dust
  • Although it is healthier for both you and your cat, it is difficult to farm corn in a sustainable way, so it might not be healthier for the environment

2. Fresh News Recycled Paper Litter

The great news about Fresh News is that it is made with 100% post-consumer recycled paper. This company has also started a recycling program called PaperGator where schools, churches and other non-profit organisations can collect paper products and get paid for it.

This paper litter is three times more absorbent than clay litter, which means it lasts much longer. It is non-allergenic and dust-free. It also contains baking soda which eliminates any foul litter box odours. The pellets do not change their shape when soaked, but they do not clump either. This means this litter needs to be changed more often than clumping litter.

  • Made with post-consumer recycled materials
  • Highly absorbent
  • Allergen- and dust-free
  • Pellets are soft and retain their shape
  • Difficult to scoop
  • Needs to be changed more often

We like the fact that this litter is made of upcycled softwood, giving a second life to old products no longer in use. It is dust-free, with minimum tracking and it is easy to clean as it clumps really well. It has a nice pine fragrance and it also contains zeolite, a mineral that captures and eliminates odours efficiently.

  • Made from upcycled softwood
  • Dust-free
  • Easily cleaned up
  • Scoops well
  • The scent- while some find it very pleasant, others might find it too intense

What makes the process of making this product even more eco-friendly is the fact that the Naturally Fresh is produced in a solar-powered factory.

The manufacturer claims that their product is highly absorbent and it will last three times longer than clay-based litter. It clumps well and it is scooped easily. The walnut shells neutralise odours and are claimed to be dust-free.
