Sunset ride

I don't buy anthroposophic cats riding horses. They were hard enough for us to train & we're just apes that hunt... But not them. Cats would have a much harder time gaining the trust of horses (they'd smell like predators that would kick-in "fight or flight").
I'd think it makes more sense for them to ride huge wolves bred for the conditions they live in, proto-wolves bread to purpose are dogs. Great Dane, Scottish wolf-hound, Alaskan Malamute & Saint Bernards... Are just the huge dogs I can think of right now.
