Though it is acceptable to flush the cat poop down the toilet, in some cases, you simply shouldn’t:
If You Are Living in Coastal Homes
If you are living along the coast where the drainage system is directly connected to the sewer, you should not flush the waste down the toilet. As mostly, they will end up in the sea, thus putting marine life in danger. Even worse, it may cause the death of some sea animals like turtles and fish because of the parasites found in your cat waste.
Problematic Plumbing System
Moreover, think twice before flushing the waste if your plumbing systems do not usually work well. If you don’t want to end up with a smelly house, you should come up with a solution. Instead of disposing of the waste in the toilet, simply scoop and dispose of these biodegradable particles in a compost pit, allowing nature to decompose for about a year and a half.
State/Federal Government Regulations
In some certain states or federals like California, the government has implemented rules which prohibit flushing waste because of its negative effects on the environment. Hence, we – as good cat parents who are all responsible for our planet – will obey such regulations wherever we are living.
