Well, as long as the ramps have good, defined footholds, then it should be good. I once got a plastic ramp that only had really no footholds at all, and that doesn't work. I had to start taping felt onto the ramp so they could get some traction on them with their nails. I eventually threw the ramp away because it just didn't work mallethead I recommend a wooden/plastic ramp with footholds that look almost like stairs that stick out of the actual ramp. As long as the pigs are able to get traction on the ramp it should work out for them. The cage sounds like a lovely piggy home, hope it works out for you!
