We use our carpeted living room for floor time. It's all been pig proofed, and we have it sectioned off from the rest of the apartment with a grid wall that folds up accordion style when not in use. When it's time to let them out we just fold out the wall, attach the ramp, and open their door. The whole set up/take down process takes less than a minute, and everything can be quickly and easily stored away when we have company or aren't able to supervise them, so it isn't a constant tripping hazard. We have brown patterned berber carpet, so pee stains aren't an issue, but odor control and hygiene is. Would putting down baking soda before vacuuming be safe for piggies? If not, what would be a safe alternative? We would like to get a steam cleaner, but haven't had any luck with finding one that is in our budget.
