why did i not discover c & c caging sooner

hi all just want to intorduce myself from the UK any UK members on here? I currently have 19 piggies at the minute including smooth coated, abbysinians a ridgeback and a rex. i have a lit made up to make a huge 6x7 2 possibly 3 layer mansion split into 4 sections for my ever increasing brood of piggies. i have used all sorts of cages from traditional outdoor type ones, indoor, pods for individual pigs, made my own wooden ones but these have to be about the best i have seen. i shall keep you updated with how i get on moving my babies 1 group at a time as i build up the cages. any hot tips or suggestions for cage accessories would be greatly appreciated.
