Litter disposal shapes the daily workload and cost. "Flushable" comes with conditions, and depending on your plumbing it may be better avoided. Here is what to weigh.
Some paper, tofu and wood litters are designed to be flushed, but there is a limit per flush, and putting several clumps down at once is what causes blockages. Mineral (bentonite) litter absorbs water and sets hard — it must never be flushed.
With a septic tank, older pipework or a low-flow toilet, it is safer to skip flushing even when the label allows it. In an apartment the drain is shared, so a blockage may affect more than your own unit. When in doubt, bag it.
Most municipalities accept it as burnable waste, but mineral litter is classed as non-burnable or landfill in some areas, so check your local rules. For odour, seal it in a bag before storing it until collection day.
It depends on the material, so yes. Note that most automatic boxes require clumping mineral litter, which is not flushable.
Topping up after removing clumps is standard practice. Once the bed as a whole gets damp, both clumping and odour control fail, so a full change is still needed periodically.
