You should never flush cat litter down a drain. Doing so will clog the pipes. Even the litters labeled flushable have caused mild clogging issues in the plumbing system. 

If you suspect your drain is clogged from cat litter. Firstly, assess how much cat litter you believe is stuck in the drain because it is a handful or so of litter. 

You can plunge the drain with the water covering the base of the plunger several times to dislodge the clog. If there are several cups of cat litter down the toilet or drain, you will need to contact a plumber to snake the drain in tandem with professional unclogging chemicals.

Word of caution: Never use a plunger used in a toilet in the bathroom sink or shower drain because it will transfer harmful fecal bacteria to your other bathroom plumbing fixtures, which are dangerously toxic to human health.

Can clumping litter be flushed?

No, clumping cat litter is not flushable because clumping cat litter is not biodegradable. The best way to dispose of clay cat litter is to place the litter waste into a strong garbage bag and dump the bag in the outdoor trash receptacle. Never put any cat litter waste into the recycling bin because it is not recyclable.  

Moreover, never discard clumping cat litter into a compost bin/tumbler because of the protozoan parasite Toxoplasma Gondii in cat feces. Toxoplasma will add bacteria to the compost pile, which is harmful to animals and humans in the surrounding environment. 

Suggestions for disposing of clumping cat litters

Most cat parents love their cats and dislike caring for their litter boxes. Consider using litter box liners to make changing your cats' litter box easier. Place the litter box liner into the empty litter box and add the clean litter on top of the liner.

Can you flush cat poop without litter?

No, never flush cat poop down the toilet. The reason is that cat feces contain the Toxoplasma Gondii parasite that is toxic to pregnant women and those who are immunocompromised. 

A pregnant woman exposed to Toxoplasma is at risk of miscarriage or stillbirth. Also, infants who survive are at risk for cognitive and mental development issues that could arise throughout their developmental years. 

If you flushed the cat feces down the toilet. The waste will sit in the septic system and cause disease that will infect the surrounding water and overfill the septic tank. 

Also, suppose the cat feces were flushed into a city sewer system. In that case, it could put many at risk of widespread contamination via the feces traveling through the sewer lines for several miles to the water processing plants. 

The majority of water processing plants are near ponds, lakes, and oceans, where marine life will be affected by the wastewater containing cat feces bacterias that are deadly to several marine life species.
