Make them fill out an application. Isn't that what some of the more reputable breeders do, since they're sending their cats home with people who are complete strangers? If this is someone who would hold Avon (or any cat) in as high regard as you do, they wouldn't mind the extra effort. And you could pose questions on the application that would give you some idea of what sort of home they would give Avon. Just a suggestion. Might be kind of silly, but hey, it might give you some peace of mind, too.
