When moderately folded in the center, this extension kit makes a great pet gate for keeping my older cat safe while work is being done in my apartment. It's perfect for a calm pet, but  I would not recommend it for an exuberant, very young cat who may be able to jump over the top. I have very narrow doorways and I eliminated the possibility of it falling over by placing it on the inside of the doorway so that the outside edges press against walls. Best part --- no assembly, no fuss, it folds beautifully and can fit in a closet.
