I feel bad for them, just when it was starting to look up for them that the hate between the two species would drive the two apart. I'm guess the change of the cat's scarf to gray was showing how grim the situation was starting to turn into while the girl was still stuck in the world where she and the cat could be together. I hope the two can hop on a plane to paradise someday, but it looks like the community will have to change it's outlook on their relationship before paradise can really be a place they call "home". Very great animation even though most of it was panning still-images. It drives home the point that we should judge a person's relationship with someone else as bad just because they're different.
I cant wait for step 5. 10 and 5
