New cage is on its way - simple 2x4 w/2nd level. I ordered it online and comes with everything to put it together as pictured below (except mine is green), but I was wondering about the ramp. I've browsed a lot of pictures in the galleries here, but haven't seen any ramps like this. It looks like coroplast with "steps" made along the way. One thing I definitely want to do is add sides, possibly use grids as some of the pics I've seen. Any other suggestions to make it safe for my 9 & 12 wk old piggies? Does the ramp look too steep? I thought about placing a rectangular tunnel under it at the base so they can still have a run-through and, at the same time, reduce the steepness of the ramp. I guess that would be like the upside down grid. Also, do you think the ramp should have something added for traction?Thanks! Any advice is appreciated.
