It can be such a pain to find the best clumping cat litter, and when you can't, you're left with a complete mess in your cat's litter box. When you have such a busy schedule, it can be hard to plan for time to give the litter box a complete clean. There are a few different options for how to best deal with this situation. Of course you could switch to flushable cat litter just to be able to dump it in the toilet, but these litters can be more expensive.
An even better solution would be to consider purchasing some litter box liners. Sift Clean Sifting Litter Liners are available for incredibly reasonable prices. You place a single regular liner down in the litter box and then place the sifting liner, which has multiple holes in it, on top. You can then use whichever litter, clumping or non-clumping, you would like. When it comes to the time for cleaning the box, all you have to do is grab the sifting liner and remove it, thereby also removing the waste and leaving the clean litter behind. In this process, you do not have to touch any of the waste product because that's the purpose the sift liners serve.
As far as litter products go, this is one of the few that truly lessen stress for you and your cat. Since cats love clean litter boxes and can even become a bit irate when theirs hasn't been sufficiently cleaned, an easy fix like litter liners with holes is simply perfect.
