Hi people! The thing is, I ran into a manga, a while ago, that looks exactly like Inu x boku SS but with cat girl (I guess it was cat). Unfortunately I don't exactly remember the title of the series but I remember it was similar to Inu x boku SS.That has "boku" and "SS" in the it's name. I tried to search neko x boku ss and it's variation but zero result. Maybe somebody no the correct name of this manga.

Probably Kudamimi no Neko

Thank you, this is indeed what I was looking for!
