Important Points to Consider

Just because you see a cat litter product is flushable, it doesn’t mean it is automatically good. There are some things you need to consider before choosing your own trusted flushable cat litter. Here are a few:

  • Comfort: Composition: is it plant-based, corn-based, or wood-based? Most flushable cat litters are biodegradable, which means they are made from organic materials, but some may still contain allergens. Check the label to see.
  • Clumping: Is still very crucial as non-clump litter is very hard to clean. However, go for the cat litter whose clumps need not be broken down or dissolved first before flushing. Those kinds require loads of time and effort and not at all suitable for the ones on-the-go.
  • Fragrance: Some cats prefer pleasant smelling litter, while some hate it. You would know better as a cat owner. Buy one that has (or hasn’t) a smell your cats will enjoy.
  • Tracking: Cat litter going where they shouldn't is such a pain to clean up, so low tracking litter should be on your top priority.

How do you Dispose of Cat Litter?

First, however, let us first discuss how cat litter is supposed to be disposed of. As mentioned earlier, it does not do the earth good when we simply mix cat litter with all of our solid waste. Sadly, this is what a lot of cat owners are used to. Worst would be disposable litter trays that generate so much waste so quickly.

In countries where the plumbing system is really good, all variants of cat litter could be flushed down the toilet – this is an alternative kinder to the environment. In some countries where plumbing is not that good, you really need the special kind of flushable cat litter to make this work.

Can you put Cat Poop Down the Toilet?

Simply answered, yes - cat poop can simply be flushed down the toilet, so a lot of our lives would improve dramatically if we could just train all cats to go in toilets and flush it down themselves. This requires intensive training, though. It would be a lot easier to just purchase flushable cat litter with all the benefits of normal cat litter such as clumping and odor neutralizing, only with the convenience of being able to flush the scooped out waste when it’s time to empty out the litter box.

Flush, flush and away!

To close, the best way to land on a flushable cat litter is to try a few ones first. It may be difficult to persuade your cat to try a new litter every so often, but it is the only way you can assure your cat is using a litter that’s best for him/her.
