I'd use 6" flex pipe instead of the ramp. I have pipes in my court varying sizes and angles it's good enrichment, plus no chance then of them falling/ jumping of sides, especially if in future you had kits in there...Im planning on building a full court with pipes and stuff in, what I am doing with the ramp is putting it on a hinge with a latch on the underside of the upper level so I can lift it up and latch in place to split into 2 seperate areas to assist with cleaning the hutch. I have also cut another 2 pieces for a sleeping area wall and door downstairs to replace the small mesh one at
