Huh... now see, to *me* those pictures are day and night as to which is which - the one on the left, if you look closely, you'll see a line of costumed characters that are miniscule when compared to the castle that they are in front of. In the left side... AAAAARGH I CHOSE THE WRONG IMAGE!!! I had chosen an image that had Walt walking through the gate :( For real-world scale comparison, the archways on these two castles are the same size.

Pictures-wise; Disneyland is flat and grey; Disney World is Tall and White :)

Not only do they put out hundreds of mouse traps, but they also have hundreds of stray and/or wild cats that come out at night to patrol the grounds - you can occasionally find one during the day, but you'll never get to touch it :)
