The other room is more like a cat playground, with trees for climbing, a water fountain and litter-box facilities.

Shaped like a manta ray, it swoops through the trees on translucent wing membranes. We get a glimpse of glassy fangs unfolding from its mouth like cat-claws, then the cannon blows it into chunks.

Here the world drops away. The only sounds are the occasional meow of a cat and the wind rustling through cottonwood trees.
