 If you liked Kanojo to Kanojo no Neko |  ...then you might like Byousoku 5 Centimeter |
the both are from the same director, and the both are same stile. For me they're just similar.
Chobi and Mimi, cats from Kanojo to Kanojo no Neko are also in Byousoku 5 Centimeter.
Both are visually beautiful and share a similar sense of quiet beauty and melancholy to them. All of Makoto Shinkai's works (Tooi Sekai, She and Her Cat, Voices of a Distant Star, The Place Promised in Our Early Days, 5 Centimeters per Second) present the pursuit of an unattainable goal and a visually stunning contemplation of loneliness. Both of them have wonderful music performed by Tenmon.
