Cat Litter Uses in a Prepper World

Storing kitty litter is not for just the feline lovers. In fact, cat litter has some very practical uses in the prepper world and its uses may go beyond what we expect.

The main ingredient that makes cat litter absorb so well is bentonite clay and is made of aged volcanic ash which gives it a very unique ability to produce an electrical charge when hydrated. Upon contact with fluid its electrical components change, giving it the ability to absorb toxins. According to Wikipedia, bentonite can also be used as a desiccant due to its adsorption properties. Bentonite desiccants have been successfully used to protect pharmaceutical, nutraceutical and diagnostic products from moisture degradation and extend shelf life. In fact, in the most common package environments, bentonite desiccants offer a higher adsorption capacity than silica gel desiccants. Bentonite complies with the FDA for contact with food and drugs

When purchasing cat litter to be used for preparedness matters, ensure that you choose the non-clumping, unscented clay litter where the active ingredient is bentonite to help you acheive the best results.

Here are some ways to incorporate cat litter into your preps.

  1. Use it in your vehicles – Having a bag of cat litter in your emergency vehicles can help the car gain traction if it happens to get stuck in the snow. Sprinkle a small amount on the ground before you get out of your car for foot traction in icy conditions. Further, sprinkling it around icy high frequented areas can also make sidewalks, steps and driveways more safe. This would be a great natural alternative to salt during the winter.
  2. Use it in your sanitation kit – This absorbent material assists in absorbing liquids and smells when using a portable toilet.
  3. Reduces mold and it’s smell – Cat litter may be used to absorb small amounts of water that leak into a basement after a heavy rain or to help remove musty odors. It can also be used in your storage closet, tent or any other area of the home to prevent the musty smell of mold. Store clothing, linens, books, papers, camping equipment etc. with 1/2 – 1 cup of cat litter tied up in a sock or pantyhose to prevent mustiness and mold.
  4.  Evict moles and rodents – Moles and rodents loathe the smell of cat litter. Pour some into the entrance of one of their tunnels and watch the exodus! This would be a great item to have to protect your long-term food storage from rodent infestations.
  5. Controls algae in ponds– For fish pond owners, this method works wonderfully to get rid of algae in ponds. Use about one pound of cat litter for 2000 gallons of circulating pond water. It is said that the water may turn muddy at first but it will clear up in 24 hours. Again, ensure that you have purchased unscented cat litter where the active ingredient is bentonite.
  6. Eliminates odors – Put cat box filler into ashtrays, smelly shoes, at the bottom of trash cans, etc to reduce odors.
  7. Reduces oil spots – To lessen staining from fresh oil or grease spots on driveways, sprinkle on clean cat box filler, wait a few minutes, and sweep off. Dispose in the same manner you would dispose of used oil. You may have to apply a second sprinkling. Use a soft brick to grind the cat box filler into the oil. You don’t have to bear down too hard, just maintain a steady circular motion to achieve the best results. When the filler is reduced to a fine powder and remains light in color, you will have removed all but the final residue that clings to the voids in the surface. This light-colored residue will lighten further the longer it is exposed to the sun. Be sure to dispose of oil-soaked cat box filler as local laws require for disposal of used oil.
  8.  Great in the garden – Mix an equal part of soil and clean cat box filler, proceed to plant your flowers, shrubs or vegetables. Your soil will remain moist providing for better root development. The litter will retain the humidity at root level. It can be used safely on any type of plant.
  9. Removing radioactive toxins from produce. One of the easiest ways to minimize the effects of radiation is knowing where our food comes from and limiting our exposure to radioactive foods and water sources. Daisy Luther explains that Calcium bentonite clay is another natural substance that actually absorbs radiation. Interestingly, calcium bentonite clay has a uniquely strong negative ionic charge. When activated with water it works like a strong magnet, absorbing anything with a positive ionic charge (i.e., toxins, pesticides, radiation). The clay captures these substances and removes them as it is eliminated or washed off.” To wash produce with Bentonite Clay: Mix 1 part Calcium Bentonite Clay to 8 parts of purified water in a large non-metallic bowl. Toss your produce in this clay water, making certain the produce is completely covered, and let it sit for 10 minutes. Rinse well with more purified water. Read about nuclear preparedness.

    In Tess Pennington’s story “Uses for Cat Litter in a Prepper World” in Ready Nutrition 12/2011, she said Rodents loathe the smell of kitty litter. Tess said “When buying cat litter for prep matters, choose non-clumping, unscented clay litter where the active ingredient is bentonite for best results. We need HELP! Please send me brand names, manufacturers, distributors as soon as possible. Thanks so much! L. Reagan

    • L. Reagan,

      All you need to do is go to your local grocery store and when looking at the cat litter brands, check the active ingredients on the back of the package. If you are interested in buying larger quantities of cat litter, do a google search for bulk quantities of cat litter.

      I hope this helps!

    50/50 in the garden? That won’t make bricks?

    I’ve got sandy compost from the dump and it’s great compost but has trouble retaining moisture. I’ve got a ton of raised beds.

    I was going to buy vermiculite but the kitty litter is cheaper.
