So no dog to cat but ape to human? Just doesn't make sense.
Sorry, I wasn't terribly clear. What I meant was that changes as large as a cat to a dog (they are related) within one generation does not happen. That is not how changes from one taxon to another occur. The change is gradual, and by that I do not mean gradual in time, evolution does not proceed at a constant rate, I mean that the changes are small, very hard to see, and cumulative.
All changes are the result of small, cumulative changes at the species level.
