I like the old appearance of most animals more than the "modern" appearances. I think the features back then were prominent enough to be recognized, but not so exaggerated that they were causing health problems, especially with brachycephalics.
Why do breeders think the persian looks better with that flat face?
Why do they think the new siamese are better than the old ones?
Why do they have to play around with animals at all?
This page shows a little, particularly with Persians too but it may step a bit into IMO territory, especially for those on the site who prefer the flatter faces or other breed-specific new traits: http://messybeast.com/ultracat.htm
