I use your mod as a dino housing/display place. I use a mod called Metal Cages which pretty straight forward. For the small dinos/birds, I built cages on your floors following the square/rectangle lines. The length/of the Metal Cages mod doesn't quite match your floor lines but close enough.

It would be great if you can add a cage like component that matches your floor lines and add additional snap points to hold it. I don't know how to add an image hear so you can see what I mean but I hope I explained it clearly.
