  5. High absorbency: Cat litter made from natural materials such as walnut, paper and corn are tremendously absorbent materials. No need for added chemicals when you have a renewable resources doing the work sufficiently!

Speaking of materials, below we discuss the different types of natural kitty litter that are available for purchase.

Different Types of Natural Cat Litter

Natural litters can be derived from a variety of materials and blends of ingredients. A good eco friendly cat litter will be made up of one or more of the following materials:

  • Wood
  • Corn
  • Wheat
  • Grass
  • Pine
  • Cedar
  • Paper
  • Walnut

Sometimes a environmentally friendly cat litter may contain two ingredients, like corn and pine. Even if a litter is made from a blend of multiple natural ingredients, it’s still considered to be natural. If a cat litter has a mixture of wood and crystals, for example, it’s no longer considered to be natural because it’s not completely biodegradable or eco-friendly.

5 Components to Look for in a Natural Cat Litter

You’ve decided you want to try out a natural litter for your feline friends. We know there seems to be an endless list of eco friendly cat litter options. To narrow down your choice, here are some more components to look into when picking out a good natural kitty litter.

  1. Pellets: Natural cat litter is widely available in pellet form. Pellets are nice for cats with long hair, and they tend to be highly absorbent. Often times eco friendly pellet litter can also be used for guinea pigs, ferrets and other small animals.
  2. Small granules: If you buy a natural cat litter with small grains, you can bet that they will have a soft consistency which will be gentle for any cat’s paws. Small grain litter also works in sifting and mechanical litter boxes.
  3. Flushable: A majority of environmentally friendly litters are flushable. If you like this idea, you’ll want to choose a cat litter that specifically states it can be flushed. Be sure to check your litter’s instructions before flushing. Some flushable cat litters are not safe to be disposed of via septic system.
  4. Additives: Natural kitty litter will be free of all additives, including fragrances, chemicals, silica dust and dyes.
  5. Clumping: If you like a litter that clumps for easy scooping, you will want to choose a eco friendly cat litter that clearly states that it is a clumping formula. If it isn’t labeled as clumping, you can assume it’s non-clumping. Keep in mind that pellet litters will not clump.
