We have two cats. We use Purina Tidy Cats, lasts ages it you scoop daily. When I was pregnant Shel did it 99.9% of the time (unless I needed it done while she was at work!), but now we take turns, whoever doesn't feed Jazz at night, the other person does the litter and takes the kitchen bin out. We change our small kitchen bin each day, put the littler scooping in it, and put it in the big bin. They're indoor overnight and outdoor during the day.
