If you are pregnant, DO NOT scoopy your cat litter box yourself. Though rare, cat feces may contain a parasite called Toxoplasma Gondii. This parasite may cause spontaneous miscarriages or induce congenital birth defects. Rather, have someone else in your household perform the chore.
As it does with all litter boxes, waste will eventually soil the sides and bottom of the Biddy Cat litter box. If this waste is below the litter level, there’s no problem because it remains covered. If it’s above the litter level, we recommend cleaning the surface of the box with a disinfectant wipe. At least twice per year you should empty the box completely and wash it well with soap and water. To eliminate any residual odor, we then recommend filling the box (to at least the litter line level) with a dilute solution of bleach (about 1 part in 20 to water) and letting soak for 15 minutes or so. Rinse, resoak with clean water, and then dry. There will be no chemical residue or bleach smell to bother your cat (standard practice amongst aquarists is to soak fish aquarium decorations in a dilute bleach solution to kill algae, rinse, resoak, rinse and return to the tank with absolutely no ill effects to the fish).
Open the top of an empty milk or orange juice half-gallon carton and use it to hold the waste you scoop from the litter box. The top is easily sealed by folding over to completely contain the odors. A partially filled carton may then be stored, odor-free, spill-free, and is easily reopened to be used again. Tap the carton on the ground to further compact the contents to provide room for more waste. When completely full, simply reseal the top and drop in the garbage. As well as a sanitary and convenient way to handle the waste, you have the recycling factor of using the carton for one more purpose before discarding (no need to buy additional plastic garbage bags). Not to mention the additional health advantages of drinking more milk or orange juice!
Place the carton from "Reuse & Recycle" above, along with the litter scoop, in a standard plastic mop/cleaning bucket. This provides an easy way of transporting to and from the litter box, is an additional litter trap, and is a sanitary way to store the litter scoop.
We use a small, free-standing folding room partition to isolate our litter box from view and to provide privacy for our cats without making them feel claustrophobic (which they really do seem to prefer).
There are no two-ways about it ... litter gets stuck on your cat's paws and they track it everywhere. There are various products available which attempt to remove the litter from their paws (typically some sort of plastic grating or pad). However, we have found that a carpet remnant (usually available at most home improvement or flooring stores for cheap) works as well as anything else we've tried. Just get a piece which is sufficiently large that your cat must walk on it when exiting the litter box. Most cats are perfectly comfortable walking on carpet, whereas we have found that our cats tended to avoid, by jumping over, the plastic litter trapping grates we've tried.
