Aria The Animation, Kanojo to Kanojo no Neko: Everything Flows Recommendations
Although completely unrelated in setting, both shows give a very similar impression. They both offer a feeling of comfort, and deal with relatable issues many have gone through.
Aria might be a bit different in that it has uses much comedy, but overall, I think both shows have a similar tone and are trying to tell similar messages.
And they're both great shows if you like cats.
