PrettyLitter is non-clumping. The super dry silica gels trap the odor inside the crystals and keep it in the granule. Just mix the litter to avoid early saturation and scoop the feces only. Once it starts to give off a smell, it turns into a slushy consistency and the urine starts to pool at the bottom. This means it is time to switch it out for a new bag. Just throw it away like you normally would and replace all of the litter every month. Don’t be alarmed if the litter gradually turns yellow over time, this just means PrettyLitter is doing its work to trap and absorb odors. It should be mixed daily to allow the crystals to trap the moisture and scoop the feces only.
