Flushable cat litter is litter the maker says can go down the toilet. That’s a label claim, not a promise that your plumbing, septic tank or local water system can handle it.
Don’t assume a litter is flushable. Never flush clay litter. If you have a septic system, the EPA says to flush only human waste and toilet paper, and specifically lists cat litter among items never to flush. For other litter, follow the package disposal directions and your local wastewater rules. When in doubt, bag it and put it in the trash.

What “Flushable Cat Litter” on a Label Means
It means the maker markets the litter for toilet disposal under its stated directions. It doesn’t tell you whether your plumbing, septic system or local wastewater utility allows it.
When Not to Flush Cat Litter
- Clay litter: don’t flush it.
- Septic systems: the EPA says cat litter should never be flushed into one.
- Local wastewater rules say no: follow your utility’s disposal guidance.
- The package says not to: follow the product directions.
- When you’re unsure: put it in the trash rather than testing it in the toilet.
What California Requires
California doesn’t ban litter from being sold as flushable. Fish and Game Code §4501 requires every cat litter sold in the state to carry language discouraging disposal in toilets, gutters or storm drains. The statute says the requirement aims to reduce flushing of cat litter and feces because of concerns about T. gondii reaching sea otter habitat.
How to Bin Cat Litter Instead
Scoop into a bag, tie it and put it in the trash. A disposal pail keeps scooped waste contained between trash days.
The Litter Genie Standard Pail holds scooped waste in a bag roll inside the pail. Many reviewers say it cuts down on smell where the waste is stored, and it comes with a scoop.
Panther Armor Compostable Cat Litter Bags are unscented 13 x 9 inch scoop bags, 100 to a box. Don’t put the bags or cat waste in a home compost pile.
