Advantages of Flushable Cat Litter

Environmentally Friendly

As many cat owners are typically aware, tons of plastic bags are constantly used to dispose of conventional cat litter. This contributes to the amount of garbage that goes into landfills, where it can normally sit for many years without being properly disposed of.

This can cause overfilling of landfills and can also be the cause of strong odors permeating from landfill sites. Using flushable litter will help to reduce the amount of landfill waste. By using cat litter that is flushable, you can treat cat waste as human waste and reduce your heavy environmental footprint.

Easier to Clean

One of the biggest reasons that flushable litter was invented was to make it more convenient for cat owners to clean their cat’s litter box. Instead of having to dump your cat’s waste into a plastic bag and then into a garbage bin, you can simply place the clumps into the toilet and wait for it to properly break down so you can flush it.

This will become especially convenient for cat owners who live in an apartment since they usually have to go a long distance in order to dispose of cat waste. Flushing your cat’s waste can also eliminate the unpleasant odors that would usually occur as a result of throwing away your cat’s waste normally.

In this case, corn-based cat litters should be avoided entirely in order to prevent aflatoxin from harming your pets.

While flushable litter could seem like a convenient and environmentally friendly alternative, parasites are also an entirely discernable issue. Paper cat litter products
