Two people, a cat, and a venerable bunny with a large cage. Litter and shavings usually account for one full bag a week, as we can’t really keep it around smelling in our apartment. Our cat has some medical stomach issues with diarrhea, so scooping only goes so far (he’s on special vet assigned food). Its about one bag a week for us excluding pets, with an extra full bag of the previously mentioned dry garbage every 3 weeks. We try to keep things low and recycle where we can.
I may also be overestimating a little bit right now, since we’re in the middle of spring cleaning, but even then most spring cleaning stuff goes to the free store, not the trash.
