Did Hagrid apparate? And the smell in Mrs. Figg’s house.

Hi, 
There are two small mysteries that have been bothering me after my 
recent re-read of the books.

After Hagrid puts Harry on the train back to the Dursley's after 
their shopping trip, Harry blinks and Hagrid is gone. The only 
explanation seems to be apparition, but it does not fit with Hagrid 
who never completed his education, and is not that good at magic. How 
could he be doing something that is said to be very advanced magic, 
with which many fully qualified wizards do not bother? 		

The other is a seeming discrepancy between SS and GoF. In SS is 
clearly says that Mrs. Figg's house smelled of cabbage. In GoF 
however, when they enter the tents Harry notes that the furnishing 
was similar to that of Mrs. Figg, but without the smell of cats. A 
mistake?
