withersuns asked: The cat litterbox. How often should I give the thing a good washing? With what do I clean it? Where's the best place to clean the bloody thing? I can wash it outside during the warmer months, but then I'm putting chemicals in the yard. I have access to a utility sink, but I'm worried the residue from the litter could clog the drains. I usually use bleach to clean it, but I'm worried about the toxicity and my cats' exposure to it. Thank you for considering my question(s).
No bleach! Bleach, aside from toxicity issues on its own, shouldn’t be mixed with ammonia (the main component of cat pee) because it will result in things that shouldn’t be inhaled, like chloramine gas, hydrazine, or nitrogen trichloride (depending on the amounts of ammonia and bleach).
Vinegar is a cat-safe alternative to bleach, and you can use it outside, although keep in mind that vinegar will kill plant life, so dump it over weeds or in an area with no vegetation. Litter dust and residue can clog your sink, so after dumping the litter, give the box a good wipedown before cleaning it in a sink.
Another option that can save you time and aggravation are litter box liners, as long as your cats don’t notice and/or hate the texture and refuse to use the box.
