This is a ramp I built with 2 grids put together. I just laid down some fleece and then connected the grids up to the cage where the piggies ran up and down when they wanted too. It worked very well
;-D
Nice! I think I might copy you, if you don't mind, and have the ramp going down from the second level, so they can still have access to the cage. Ahhh...Now I can put to use some of those extra grids and caging!
