ABANDONED. Book where people have cat powers; girl's brother is sick and her parents are trying this new medicine trial. It turns out that the new mysterious drug is cat bile from cat liver

[Pegii-Juno]

I cannot remember the author's name. It's in third person. It's about people who go to this group to get magical cat powers. There are two protagonists a boy and a girl. I think the boy is called Ben. I can't remember the girl's name. The girl's brother is sick and her parents are trying this new medicine trial. It turns out that the new mysterious drug is cat bile from cat liver (gross I know) and the guy responsible for pumping it out drinks it because he has a deformed arm.

When did you read it? Was it children's, YA, or adult? Author female or male? Remember the cover?
