I am pleased to have discovered there is one (1) additional brand of olive oil Rannie Wu will accept. Well, the same brand, different variety: Bertolli "Light." The were out of Bertolli "Classico," so I tried it instead.
Most of the other brands she has rejected in the past were either Extra Virgin, which I think is too strong-flavored for her, or they have a kind of bitter taste. Bertolli gets consistently good reviews for flavor and purity. Even by critics who aren't cats.
