She and Her Cat by Makoto Shinkai and Naruki Nagakawa

This was a silly little book, and (I think) the perfect follow-up after reading No Longer Human. The cats in this book can be a little goofy (one cat thinks his owner is his girlfriend) but it's a feel-good book, and I might have cried a little bit.

But, overall, all I could think about was, these people should really just keep their cats inside.
