This will definitely work. It isnt great quality though. The wood is pretty flimsy. One of the support posts crumbled when I started screwing in the step! The screws we received were also the wrong size and stick out super far on the support posts.

The openings for the cats are small too. Our adult house cats have a hard time getting in and out. 

Were hoping this can be a place for a neighborhood cat this winter - hope it lasts through the season!
