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. Use It to Even Out Your Lawn

Use It to Even Out Your Lawn

The first thing that any expert will tell you is never to dispose of used kitty litter on a vegetable, herb, or fruit garden. This is because cat waste can include parasites such as Toxoplasma gondii, which can be responsible for birth defects in humans.

Therefore, a good alternative is to use this crystal cat litter to even out your lawn’s uneven areas. Since these holes can cause anyone to trip or fall, you can easily fill them out with used kitty litter.

The same goes for sinkholes or animal holes in your lawn.

This way, the silica in your used kitty litter will be put to use without being toxic to the environment.

2. It Can Prevent Oil Spots

It Can Prevent Oil Spots

As you know, kitty litter has silica in its composition, which you could use to your advantage since it absorbs liquids. You can use crystal cat litter to soak up any oil spots or spills on your driveway.

Simply enough, apply a few scoops of used kitty litter to where your parked car might normally leave oil spots. This way, if any oil spills from your car, the crystal cat litter should be able to absorb it before finding its way to the concrete.

Of course, it can be pretty hard to soak up any oil that’s already formed on your driveway. Therefore, it’s always a good idea to prevent this from the beginning.

4- Use as a dehumidifier

Don’t throw away your used crystal cat litter just yet! You can actually use it as a natural dehumidifier to help control excess moisture in your home. Simply place the used litter in a breathable container, like a muslin bag or mesh container, and put it in areas that tend to be damp or humid, such as your basement or bathroom.

The silica gel in the litter will absorb the moisture in the air, helping to prevent musty smells and mold growth.

5- Dry out wet shoes

There’s nothing worse than having to deal with wet shoes, especially if you’re in a hurry. Luckily, you can use your used crystal cat litter to help dry them out. Simply fill a sock or a cloth bag with some of the litter and place it inside your shoes overnight. The litter will absorb the moisture from your shoes, helping them to dry out faster and preventing any unpleasant smells from developing. Just be sure to dispose of the used litter properly and avoid using litter that’s been contaminated with pet waste.

It’s important to note that this method works best for non-leather shoes, as leather can be damaged by exposure to moisture or heat. If you have leather shoes that are wet, it’s best to let them air dry naturally and avoid using heat sources like a hairdryer or direct sunlight. Additionally, if your shoes are soaked through, you may need to replace the litter a few times to fully dry them out.

Is It Safe to Reuse Crystal Cat Litter?

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.

– 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.
