look at my improved cage!

Overall your cage looks great, but there a just a few areas that might be unsafe. Your ramp has lots of sharp edges that could harm your piggies. The best way to make it safe would be to use wire-cutters to clip off the parts that stick out, then sand those down until it feels smooth. Also, the bottom of your ramp might be hard to climb since the mat only partially covers the wire. The piggies might be scared to use it, or worse they could get their feet stuck and be injured. You might want to cut the shower mat in half and cover the whole ramp from top to bottom with the two parts. Also, you should consider adding some walls to the ramp so they can't fall off. You might be able to bend the wire up to modify the current ramp.

it wasnt finished yet in that picture. since i took that, i bent the ramp to give it a side rail, and secured the mat to the ramp, making it completely covered. you may also notice the mats on the top level do not fit very snugly. I cut them to fit as well.

Ok, sorry, I was confused because you said in your first post that you just finished it- I'm guessing you forget to mention that there was still work to be done. I'm glad to fixed those problems and I'm sure your piggies love the cage.

well, they're reluctant to go into the house on the second level, but every once in a while they run around the bottom of the cage squaking and popcorning, so i think they just have to get used to it.

Ya it might be awhile till they get used of things but I'm sure they will eventually.
