Deluxe Cat Wall Mounted Boardwalk Bridge

This is a customizable Boardwalk with extra large slats that our cats love to chase each other on.

It is a 6' long Boardwalk, with 11" wide slats. Attached at various lengths are five posts that are meant to be installed into studs.

Also pictured is our weight test. We've rated this one "super duper strong." All of the brackets do need to be installed into studs for it to be this strong though.

The Boardwalk pictured has Unfinished wood.

What if I have no studs to install the shelves. Can they be installed into drywall or plaster? 
If you don't have studs available, there are other possibilities, like heavy duty drywall anchors. Home depot has packs of six that are rated to each hold 65 lbs. for under five dollars.

We've never tried these with our raceways, or fabric play place. We're not sure that they would hold tight enough. They get pulled from the side each time a cat jumps on, so we really suggest mounting those into studs.

Do the shelves come with mounting equipment?
All of our pieces come with screws, light duty drywall anchors and brackets attached. Except for our cat bridge. Because it typically sits at a doorway, we don't know where the studs are, so we include brackets but do not attach them.

What do I need to mount the shelves?
You need a screw driver, a drill, and a stud finder.

Also a level, if you want them perfectly straight.
