Indoor hutches are SO much better! Let me tell you! They can get in and out of them whenever they want. I actually bought an indoor hutch and then went and bought a dropping pan and basically, their cage is their giant litter box. It's a pain to clean though. That's why I clean the one corner they go in every night. To eliminate odor and to keep it from looking gross. But they are really much better in the long run. A tip for litter box training: put their litter box where they seem they like to go, even if it's behind the couch or something.
