This is the C&C cage we built for our 4 girls. Eventually, it will have a second level. For now, though, the girls just have one level, which is about 16sqft (2x6). And yes...I know the picture is crowded - too many piggy houses! This pic was taken when they were first introduced into their new cage (and introducing a new female to the herd), so I put four houses in there so they could each have a place to hide if they wanted time out.

Now, there are only two piggy houses so they have more room to run and move.
