Just throw it away like you normally would and replace all of the litter every month. The solid excrement is the only waste you need to scoop and dispose of. The super dry silica gels absorb the urine and odor, trapping it inside as the water in the urine evaporates out. If color change persists, you should consider consulting your Veterinarian. If you notice any other colors, thoroughly mix the litter and monitor your cat's PrettyLitter closely over the next 24 to 48 hours. Shades of yellow to olive green are an indication of typical acidity and alkalinity levels. If there is any residue on the bottom of the litter box, clean the litter box before pouring in your new supply of PrettyLitter. When the litter is saturated, typically after a month's use, empty the entire litter box's contents into a trash bag. Thoroughly mix the litter every day to avoid saturating the same spots in the litter box that cats prefer to urinate in.
When you scoop the feces, make sure to shake off the extra litter granules.
Make sure you are getting the proper 2 inches of depth. Pour the entire contents of the PrettyLitter bag into a clean litter box.
