I'm looking for the title of a romance series where the MC starts dating a cat-girl. Sounds too vanilla to find the specific one doesn't it lol. It's possibly a 4-koma but I couldn't get anywhere with that in the search. What I remember that makes it different than normal was that they were humans with beast blood. So no ears or tails but some of the behavioral patterns. Technically falls under harem since there is also a dog-girl and a bird-girl.
