I know some rescue groups will adopt some cats out - often ex ferals - as what are referred to as shadow cats where you share your home with a cat and are open to making them your companion, but ultimately they spend a lot of time out of sight, they don't actively seek affection, and over time they learn to open up more. Not to the point of being lap cats or anything, but to be happy living indoors with human companionship rather than fearful and completely unhandleable. It definitely takes a special home and a special kind of person to bring in shadow cats, especially in cases like Tilly's where one is more a shadow cat and one is fiercely demanding of their person. I would hope the rescue just didn't evaluate them thoroughly enough prior to placing for adoption, rather than lying about the condition of the cats. It's a real shame the foster home didn't take the time to get to know them better and have more foresight for potential adopters.
