Excellent cage, very well made. Bigger than I expected which was really nice to find out. My rat loves it! Best purchase I could have made and the price was right! I searched through several cages on Wayfair and other websites and chose this one because it had the most features that I liked. I would definitely recommend this for anyone that needs to upgrade for their adult rat. Bar spacing is 1 inch so would not recommend for young rats. Very easy to put together, but parts are not labeled so gotta pay attention to the pictures and how it says to put it together because it matters.
