Bottom Line

For those who seek a flushable and eco-friendly cat litter, this wheat-based brand clumps faster than clay and is easier on the paws.

Cat owners have a dizzying number of choices when it comes to litter. Some brands emphasize odor control, while others promote their clumping power or eco-friendliness. One major consideration that is often overlooked, however, is flushability. A flushable cat litter means the owner can safely dispose of soiled litter in a toilet without damaging the sewer system. Not all cat litter brands are considered flushable, but it's a good feature to consider when dealing with multiple litter boxes that need to be changed frequently.
