When we first got this, our piggies were small enough to dart into the holes and use the barn as a hidey-hole, so we took it out for a couple of weeks until they got bigger. But it's sturdy, holds a lot of hay, and the kids love the way the pigs go to the "hay barn" to eat. For future changes, I'd suggest making the roof easily removable for easier cleaning, but it's a great little hay rack!
