yes I have made these cages. Heres a tip..once u've got it put together the way u want it..secure everything with zipties.
they are great cages and provide lots of room for your piggies. the initial expense is high because u need so many pieces. Remember u don't have to make a bottom, just use the coroplast as ur base to save on cage pieces. The site won't let me post pics because it says I'm full to capacity (weird) but heres a great website and youtube videos with lots of pics for u to chose from and plans to help u get started
good luck and post some pics when u're done
