This enormous vehicle pulls up out front. A robotic arm extends from it, grabs our recycling bin, lifts it high into the air, inverts it, shakes it violently, then replaces it on the kerb. Kitty watches the whole thing unfazed. How on earth can she be so sanguine about something which must be utterly incomprehensible? The sheer number of bizarre phenomena that #cats just accept without the slightest hope of ever understanding would drive me barmy.
