Honestly for mychocolate polish 1 yr old, she hasn't had a cage for 5months. I let her run around the room 24/7, she dosent bite wires,loves the freedom, knows where the food is, totally litter box trainedI love her for it, don't have to change her litter for 2 weeks and ithas never smelled at all in my room. (I rotate the soiled litter around)
And the great thing is I also live in a college dorm with a single room.
