The portal...
I decided to explore the bit in between all rooms again. I came to the special door. I was sure I'd seen it before, but couldn't remember. I was in a state of wonder. What could be behind it? A magical land? A world full of toona? A labyrinth of moving red dots? Bowl after bowl of chicken biscuits? Fellow cats riding tiny horses into battle? I meowed at my hooman to come and assist me urgently - to grant me entry to the magic portal. I meowed and meowed and meowed. I yowled. Finally he heeded my call. And with a cry of 'Alright, I'll open it!' he showed me the world within. There were lots of plastic bags. I sniffed the bottom shelf, then walked away.
