I keep trying to come up with the best area in my house to have floor time. One of the main problems I have is that I have cats and obviously I need to be able to have a play area that the cats can't get into. I've thought about the bedrooms (we have two) but I'm not sure I can piggy proof either of them. We've tried the kitchen (making sure to block off the gaps at the side of the fridge) but I don't think my pigs are happy with the tile floor. The living room has the normal problems of things like cords and furniture to get under/stuck in.
Where is the best play area that has worked well for you?
