Many pet owners assume that flushing cat or dog feces down the toilet is a convenient and hygienic way to dispose of it. However, experts warn that this practice can create problems for plumbing systems, wastewater treatment facilities, and the environment.
Although flushing pet waste might seem harmless, there are several important reasons to think twice before doing it.
Cat and dog feces can contain harmful microorganisms and parasites. One example is Toxoplasma gondii, a parasite that can be present in cat feces and cause toxoplasmosis. This infection can be particularly dangerous for pregnant women and people with weakened immune systems.
The concern is especially important because some wastewater treatment systems are not designed to remove every parasite or pathogen. In certain circumstances, contaminated water can contribute to environmental pollution and expose wildlife to infectious organisms.
1. Cat Feces Can Contain Dangerous Parasites
Cats can shed Toxoplasma gondii in their feces. The parasite can eventually reach soil and water when contaminated waste enters the environment.
Some treatment facilities may not completely eliminate these parasites. Research has shown that Toxoplasma oocysts can survive certain environmental conditions and pose a risk to wildlife, including marine mammals.
For this reason, cat feces should generally be disposed of according to local waste-management guidance rather than flushed down the toilet.
