I'm looking for something I thought was on here. I lady finds a stray catgirl out in the rain I think. She brings her home and she has another catgirl there already (who is a little jealous of the new cat). The lady takes the stray catgirl into the bathroom to clean her and the other catgirl can hear her shocked cries of stuff like "where are you touching?! Don't put that on me!!" silly stuff like that. Later after the stray is all clean she's cuddling with the other catgirl and when the lady walks in it shows from her perspective that they are actually normal cats.
