Her favorite destination is usually the living room, where she can hide under the couch and elude being recaptured. But lately she's taken an interest in my cage cleaning routine and wants to be in that room, instead. The first time she breached the walls on Sunday, she did so very quietly. I turned around to find a gaping hole in the grids and no pig. The subsequent two escapes were not nearly so stealthy. We managed to catch Pinni on video, and you can see she was a bit aggravated to be on the wrong side of the grids yet again. Her strength is impressive; she managed to lift two of the grids off of the floor several times. Grids are pretty heavy when they're all zip-tied together.
Similar to solving the Teach 'N Treat, Pinni understands that certain actions can get her desired results. But she still doesn't have any concept of cause and effect: she will tug on the grids to create a gap, but hasn't figured out she could just move the end piece to get around the wall, or that pushing the grids away from her will eventually create a gap. Regardless, we had a good time watching her efforts and her few seconds of freedom before she was snatched up and returned to the kitchen.
