Today I made my two little pigs their first C&C cage. Its 2x4 grids and I think my pigs love it. I find one thing very funny though. I made a lid out of coroplast, just something simple to hopefully keep out curious dog out for now. But when the lid is on the cage the girls will be very quiet and take turns hidding in their pigloo. I took the lid off a few minutes ago, and now they're busy squeaking away and exploring the cage. Perhaps does the lid scare them?
