i want to use these to build a 2 story C&C cage and basically i wanna kno if those would be ok to use and what i could use for support under them for the 2nd tier?? i have no clue where they got them at al they have had them for a while since before my husband and i got together. i hope these will be ok. i have a 2x6 main cage and i wanna do a 2nd tier of a 1x2 sleep area with a 1x3 sky walk (bridge to connect the 2 sides) and a 2x2 kitchen. i have 5 females in the main cage now and i have 2 males that i will be adding in as soon as they get neutered in a few months then i will have all 7 pigs together in the big cage. i also want to add ramps but i dont know if i want to add one ramp in the middle or if i want to add 2 ramps (one on each side)
