Great expansion kit!

This is a great expansion for any cage! It does not come with instructions but if you look at one of the pieces it has extra plastic rings in the middle of it put this in the hole you are adding the expansion on too take the J shaped piece and from inside the cage with a O ring on it snap them together (WARNING) it will be hard to get them back apart without taking the top of the cage off and alittle work. But the top of the lookout comes off and allows you to have even easier access to play with your pet. As bad as a pun as it is I really wanted to say play with your little critters LOL. Oh and if you try to put it on the side of the cage OFCOURSE you are going to have issues with keeping it upright. it does not really attach that way it is mean to the top or for adding into a more stable section of a expansion.More detail ...
