Yes but the edges may still be sharp and toenails could get caught in it...and once it's packed with poop impossible to scrape 'clean'.I was thinking about the wire mesh today - I wondering that too. Note, I have it screwed down really well, BUT... you are most probably right - this could become a real problem.
This sounds like the best plan. Mine are just plain wood, a bit slick, but they don't mind sliding a bit if there's cleat to stop the motion. Reducing the angle will help with sliding too, just put that block tall-wise, they can jump the 16", or put another next to it, laying down, for a step.Doubling up on the cleats is easy enough, but it is still pretty slick.. Maybe I'll just rough it up using a sander and/or put some non-skid tape on there. I'll experiment over the weekend and advise what I came up with.
