Not since EDS "herding cats" and Ikea cats have we seen this many cats in a commercial, though most of these are cgi-trickery from The Mill. These are here because a man so thrilled he saved money on car insurance feels like he could run with bulls in Pamplona, or maybe squirrels, but lacking those he asks his cat to join him. Since we're all suckers for cats, as everyone at Mother London seems to be, it works.
There's a 30 second too, but this 40 is better. Moar cats! Since this is made by Mother it might start a re-trend. Great. Now there's gonna be cats everywhere.
