A 2x3 with 1x2 upper level for two boar brothers, one of whom is special-needs. The ramp is carpeted for traction (industrial carpet, $2.50 a square) and the upper level has coroplast, which is covered with a towel to make it softer.
I was a little alarmed by the open grids on the ramp. I would think this could be a hazard for little piggy feet. Maybe you could cover the whole ramp?
