I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Again, I love it when this series shows Chi doing kitty stuff. Alice the Scottish fold was adorable when she went after some thrown paper, and I laughed when Chi accidentally got tape stuck to her and messed up Mr. Yamada's entire office.
On the one hand, I liked Chi's explorations less, because the cats were almost human in how they thought and helped Chi. On the other hand, Chi nearly meeting her mom was a new and unexpected development. I'm guessing the anime and manga must be fairly different, then, because I don't remember this happening in the anime at all.
