Renovations to my 2x3 C&C cage

[ryugaiden05]

I am thinking about adding a second level to my 2x3 cage. My 3 girls need a little extra space to roam around. I know the cage is small for three girls, but when I built the cage I had limited room to place it and only had intentions of having two piggies. However, when I went to pick up my second pig I had to bring her and her sister home since they seemed to not have been in the best of living arrangements. The three of them get along fine in the cage, but I am thinking of adding a second level so they can have some more room. I am looknig for some suggestions on how to do this. I need to know what type of suports and things I may need to do so the second level will hold their weight. Also any ideas on ramps would help as I do not want to make it such a steep climb for them to get to the second story. Thank you in advance for any suggestions.

I have had both types, single and 2 levels. Honestly, I (and my girls) prefer the single level. The ramp does take space away. Have you looked into the pictures of single and multi level cages to get ideas from?
