β€œA ferret, Ben! Imagine!” Theo exclaimed, doing a little skip towards the window. He was practically vibrating with excitement. He loved the thought of a sleek, curious creature investigating every nook and cranny of their apartment. "We could build a whole network of tunnels for it!"

Ben, ever the voice of reason, was sketching on a notepad. "Theo, ferrets smell. They bite. And they need constant supervision."

Theo ignored him, grabbing a cushion and pretending to make a burrow. He then started wriggling on the floor, pretending to be a ferret. "We can get a tiny ferret bed, we can play with it!"
