Can I flush TellTail with a septic system or old plumbing?
No — don't flush TellTail if your home has a septic system or older or low-flow plumbing. Put used clumps in the trash instead; the litter works exactly the same either way.
Septic tanks and narrow or aging pipes are where any litter is most likely to cause trouble, even one designed to break down in water. Bagging the clumps is the simple, safe choice there.
Wherever you live, cat droppings belong in the trash, not the toilet.
Flushable* — TellTail’s plant-based clumps break down in water, so flush the clumps a little at a time. Place cat droppings in the trash, not the toilet. Not recommended for septic systems or older / low-flow plumbing.
