this catio was a bit difficult to put together. Plus the mesh netting holes were big enough for flys to get in. we couldn't hardly put it up, as it was so flimsy. We had to secure it to the outside wall of the home plus use 2x2s to reframe it. Then we built a floor. We also had to use tin metal for the roofing as the thin plastic that came with it for the roof, wasn't realistic. basically we had to rebuild it, and add our own screening with it. Its overpriced for what it is.
