My hedgehog ABSOLUTELY LOVES THIS CAGE!!! I JUST WISH THE STAIRS WEREN’T SO STEEP!! I had to make a ramp for her to get up to the raised level. Also, the water bottle broke. Good thing I had back ups. If you’re thinking about getting an add on addition for length, I would buy the cage first. It was much MUCH bigger than I was expecting. It’s light and easy to assemble. I did have some trouble with the side panels but overall I would definitely recommend.
