how many can i fit?

[:) zoe :)]

I have been thinking about getting some moor piggies to join my two lovely ladies, right now they have a two story c&c cage, at the bottom its 2x4 and at the top its 2x2. If i was to extend my cage making the top also 2x4 how many piggies could i have in the cage

5 or 6 i think, as you add 1 side grid per pig after the 2x4
