It depends. Even if it’s marketed as “flushable” litter, there’s no guarantee against clogs. It’s not recommended for older plumbing systems or septic tanks. Plus, some municipalities prohibit the flushing of cat litter, so always check with your local ordinances before flushing. There’s also the risk of introducing pathogens into the environment, which could harm wildlife. To minimize the risk of clogs, always break apart larger clumps, and let them soak in the toilet for 15 minutes before flushing.
