It’s a bit too big for the area I wanted to put it in and I actually got it for my cat so since I have crown molding I can’t put it above it cause she can squeeze under it. However I was able to maneuver it into the space and it is staying put without being mounted! I have a loft and no bedroom door and I love my kitten dearly but I can’t deal with her 3 am zoomies anymore and this is PERFECT for keeping her in the rest of the house while I sleep. Thank heavens!
