She and Her Cat (1999)

To give it its full title, She and Her Cat: Their Standing Points (i.e. viewpoints) is an early short (5 mins) B+W anime from Dir. Makoto Shinkai. The animation is simplistic, but it's certainly not hurried and it suits the aesthetic.
It begins in springtime, then moves through the subsequent seasons to end in winter. There's a voice-over from the perspective of a male cat, commenting on his relationship with the young woman whose house he shares. It's a sweet, thoughtful and often poetic slice of observation that provides a glimpse into one example of the process by which two souls can come together.
