I made a ramp for my piggies and it turned out great, but there's one major problem.... they don't use it!! I made sure it wasn't too steep, that was a concern of mine, so I'm confident that's not the problem. It's probably just because they're still geting used to the cage, but does anyone have any ideas to getting them up to the top level? What did you guys do? And did you even have to do anything?
