Natsume Yuujinchou, Kyoukai no Rinne (TV) Recommendations
The main characters are human boys with slight supernatural abilities when it comes to demons/spirits/ghosts. Despite being human, they can see and interact with them. Both their grandmothers were exceptional at dealing with demons/ghosts and strangely, their grandmother is the only relative that is given importance or even mentioned in the anime. They both have "pet" cats which are actually demons that take on a cat form, but can transform into a larger more threatening form when needed, although Nyanko sensei and Rokumon have completely different personalities.
These animes sort of have their own plot per episode so you can enjoy a fresh story that
