A Step-By-Step Guide on How to Reuse Crystal Cat Litter

Because crystal kitty litter contains silica gel, you might find it a bit challenging to recycle. This is because silica doesn’t decompose, which doesn’t exactly brand it as a green option.

Still, there are a few ways you can reuse crystal cat litter without causing any harm to the environment.

1- Absorb Oil Spills efficiently

  • Place a few scoops of used crystal litter directly onto oil spots on your driveway, garage floor, or parking area. The silica gel will help absorb and soak up the oil.
  • Let it sit for a few hours or overnight to give the litter time to work. The area should look cleaner when the litter is removed.
  • Sweep or vacuum up the used litter once it has absorbed the spill. Properly dispose of the contaminated litter.
  • For larger spills, you may need to repeat the process a few times using fresh batches of litter until the area is free of oil.

2- Use as a Dehumidifier

  • Place used crystal litter into breathable containers like muslin bags, tied socks, or mesh pouches. Avoid using bags that will trap moisture.
  • Position the pouches of litter in damp, humid areas of your home like basements, bathrooms, closets, etc.
  • The silica gel will help absorb excess moisture from the air and prevent mold, mildew, and musty odors.
  • When the litter stops absorbing moisture, after a few weeks, replace it with fresh used litter.

3- Dry Wet Shoes

  • Place used crystal litter into a sock, bag, or other permeable container.
  • Insert the pouch of litter into your wet non-leather shoes to absorb excess moisture.
  • Let your shoes sit overnight with the litter inside. The silica gel will draw out the water.
  • In the morning, remove the litter and dispose of it. Your shoes should be much dryer.
  • For very wet shoes, repeat the process with fresh batches of litter as needed.

4- Kill Poison Ivy

  • Take used crystal litter and sprinkle it directly onto poison ivy plants infesting your yard.
  • The sharp edges of the litter crystals will cut into the plant and destroy the waxy coating on the leaves.
  • This smothers the plant and stems its growth. Within a few weeks, the ivy should die off.
  • Avoid using litter contaminated with pet waste which can spread disease.

5- Pest Control

  • Sprinkle used crystal litter around the perimeter of your garden beds and anywhere slugs or snails are a problem.
  • When they crawl across the sharp, jagged edges of the litter, it deters slugs and snails.
  • Reapply after rain or watering. The abrasive crystals irritate their soft bodies, keeping the pests away.
  • Do not use litter that contained pet waste which could infect your garden soil.

6- Odor Absorber

  • Fill permeable pouches like tied socks or muslin bags with used crystal litter.
  • Place the pouches of litter in any area where odors are a problem like closets, basements, bathrooms etc.
  • As air circulates through, the silica gel will help absorb foul odors, leaving fresher air behind.
  • When the litter stops working, replace it with new material.

7- Fire Starter

  • Only use clean, unused crystal litter for fire starting purposes. Using soiled litter can create toxic fumes or odors.
  • The silica gel is highly flammable and lights quickly with a spark or match.
  • Place a small mound of unused litter under your kindling then light it to help start a campfire or fireplace faster.
  • Have water nearby and never leave fires unattended when using this accelerated fire starting method.

It’s only safe as long as you don’t dispose of used cat litter in gardens with edible plants. As we discussed before, crystal cat litter isn’t biodegradable, so it can be harmful to your plants.

Also, it’s a bad idea to put animal waste in your garden because of the parasites it might contain. So, you should stick to the safest options when trying to reuse crystal cat litter, which we already approached in the previous section.

How To Recycle Unused Cat Litter?

Unused cat litter can be much safer to recycle because it lacks animal waste. Yet, where you reuse it mainly depends on its type.
– Clay or crystal cat litter: Best for soaking up oil leaks caused by your car or even lawnmower
– Wood or paper cat litter: Great for use around plants to help the soil absorb more water
– Wheat or corn-based cat litter: The perfect option to put in your compost container

Can I make my own cat litter?

Luckily, you can create your own version of cat litter with items that should be normally available in your household. This way, it’ll be a chance to recycle different stuff in your house and save a few bucks as well.

For instance, you can use shredded newspaper or old paper that you’d otherwise throw in the garbage. These should make your cat more comfortable. However, they might be a bit tricky to clean up since they aren’t as absorbent as other cat litter types on the market.

Still, the best thing about using old newspapers as cat litter is that you recycle it for the third time. Your inner environment activist should be thrilled at the idea!
