How long do Modkat Reusable Liners last?

Reusable liners last up to three months depending on how many cats use the litter box, how much litter is used, and how ferociously your cat(s) scratch. To get the most out of your liners, we recommend cleaning with mild dish soap and water monthly. Be sure to let the liner dry before putting it back in the box. Replace the reusable liner when there are signs of fraying tearing or excessive odor.
