I’m in an apartment also, and I’ve done boxes two ways. San Francisco has city wide composting, right?
We used to have a plot at the community garden, so I would compost everything (I use pine pellet litter but I think all bunny safe litters are compostable). During that time, I used a litter box screen, and every 2 days I would dump all the hay and poop from the top of the screen into a 5 gal bucket with a lid (which also had our veggie scraps, coffee grounds, etc), and then scoop out the pee-soaked bedding into the bucket as well. I would do all this in the kitchen so I could sweep up afterward. I would also top up hay in the kitchen so I could sweep up. I keep my hay in a big plastic bin.
After a few years we gave up our garden plot, and our city doesn’t do composting. We have a cheap source of pine pellets and hay, so I switched to the lazy version where I just take the entire box to the trash bins and dump the whole thing every other day. Now when I top up the hay I usually just get the bin as close to their box and hay rack as possible.
Thinking you could prob use the 5 gal bucket system since you likely have composting available to you? Or I imagine you could just take the whole box down to the compost bins, but depending on how easy they are to get to it might be easier to use the bucket so you don’t have to venture down to the bins so frequently?
Having a big litter box helps keep everything contained. I think most of the mess comes from me topping up the hay vs. the buns actually spreading it around. I use pine pellets plus a fluffy layer of hay and there really isn’t any smell I can detect with dumping it every other day (and I’m in a studio apartment so in the same room as the box all the time).
There are these rubber brooms that seem to work really well for cleaning up hay on carpet. I have a hand one that helps for keeping things tidy between vacuuming, but I think a full size one would be great.
