Whoopee ti yi yo! At the end of this 2006 video is an ad for a company that is long gone, but the gitting along of little kitties lingers on.
As any feeder for a feral cat colony can testify, herding cats is easy under the right circumstances. “Harder than herding cats” is just a negative stereotype. If you consider herdability to be a good thing, that is, which I suspect many feliphiles do not.
(If the proximity of giant hooves to little furry heads makes you squirm, rest assured that cats and horses in this video were filmed separately.)
