[FONT=Courier New][FONT=Microsoft Sans Serif]I've noticed in quite a few pictures of the cages with more than 1 level, that sometimes sides aren't put onto ramps - I'm not ready to be making a multilevel cage yet, but if I decide to in the future I'd like to know how neccessarry the ramp walls are? I'd e very worried about a piggy falling off the side, but maybe I'm missing something like the potential to get stuck if I do put edges.[/FONT] [/FONT][FONT=Microsoft Sans Serif]Is there anything I should be aware of with the ramps?[/FONT]
