Flushable Litters For Cats Buyer’s Guide

Cat litter with clump

You can find various kitty litter types in the market. But the traditional sand or clay litter is the most commonly used type because it is suitable for the feline’s natural habits. Other than that, it is quicker to dispose – all you have to do is dump it in the trash after use.

However, if you’re a cat owner living in a high-rise building or apartment, using a traditional litter may become a problem. Since these types of houses don’t usually provide access to outdoor garbage units, it will be hard for you to keep the waste box clean.

Yes, you can still leave it in the trash. But after a few days, you will smell an unbearable odor coming out of it.

Fortunately, flushable cat litters are already available to help you out.

Here are the essential factors that you need to consider when looking for the best product:


Choosing a non-tracking cat litter is essential because it won’t be stuck on your pet’s paws. Since larger granules tend to track less than smaller ones, you should choose a product that comes with it.

Organic materials

Yes, flushable cat litters are made of eco-friendly, biodegradable materials. But you have to take note that each of them has different advantages and disadvantages.For instance, kernel corns are excellent for cat litters. But they may affect clumping and odor control. Another example is clay. It can control the clumping and odor, but the waste can become dusty.Don’t worry, though. You can buy a product that comes with natural materials mixed in together to provide maximum benefits.


There’s no denying that both their pee and poop have an unpleasant smell. That is why it is essential to look for a scented product to control your pet’s urine and feces’ odor, no matter what type of cat scrap you buy. This strong odor can cause health complications for you and your whole family, so make sure to pick a brand with great odor-control features.


Buying a product that can produce a big amount of dust is not a good idea because felines have a sensitive sense of smell. They can inhale the dust and cause breathing problems and allergies.And it doesn’t end there. You and your family can also have serious health conditions when you breathe dusty air. That is why you should look for a dust-free flushable cat litter. But you should remember that dust-free doesn’t mean that it will produce zero dust. You will still see a small amount, but that’s better.


Clumping is significant when it comes to flushable cat litter. That is why you should make sure that the product you will buy clumps well. Enough clumping will prevent the box and its surrounding from becoming messy when used. If the clumping is very weak, the waste will be challenging to clean.

Granule Size

You will find a variety of granule sizes when buying a cat litter, so this factor is also essential.Look for a product that suits your pet’s needs.If they have soft and gentle paws or their claws are recently removed, you should buy a brand that comes with small granules, almost like the texture of sand. Small, fine granules are also easier to flush compared to larger ones. However, as mentioned earlier, it can produce a great amount of tracking and mess. You can buy a trapping cat litter mat as a solution, though.

Home’s septic system

If you are using a septic tank for your toilet, you should look for a specifically designed product. This factor is vital because if you use a product that doesn’t support septic tanks, your pipes will have a major blockage. On the other hand, flushing the litter down the toilet is not recommended if your drainage system is connected to the sewer. It can end up in the sea and harm marine life.

Things to remember when buying cat litter

Cat litters are all safe to flush, except the clumping clay one. It can damage your plumbing in the long run, so you should avoid it.

Clumping clay litters are made from sodium bentonite. They are very absorbent and form a cement-like consistency when mixed with water.

Because of this property, clumping clay litters became very popular and effective. However, this property can also destroy both your septic and plumbing systems, so don’t use it.

It is not a good idea to flush non-clumping litters in the toilet, too, even if it’s allowed. They may not solidify or expand once they’re mixed with water, but they can still block and damage your plumbing in the long run.

Always use a biodegradable or flushable cat scrap if you’re using a septic system. It is the most recommended type of cat litter that is safe to wash down.
