Kaji gets free roam when I'm away. We started with my room, added the hallway, and eventually he got the whole apt. I did have to take back the kitchen when I kept finding the trash all over the floor.
Other than the kitchen, nothing is off limits.
Ok... That is until recently. Kaji has started to poop in my room as soon as I leave for work. I crate him before I leave, and my mom lets him out to have free roam after she's done with work. I'm hoping we don't have to do this forever, and Kaji can earn his free roam again.
